Suspend to ram Dell insipron 6000 (probably easy)

Question

Hey,
I'm having some basic problems with the whole suspend to ram operation.  As a new user to configuring this by hand, I'm a bit lost at where I should start.  So this is what I have so far.
I have installed Klaptop, and it has the suspend option, but after suspending, it doesn't resume.  (It powers back on to a black screen only where I can't do anything)
I have installed pm-utils.  pm-suspend suspends the computer and then on resume just goes to the same black screen like klaptop does.
My daemons  are
DAEMONS=(syslog-ng cpufreq !network netfs crond kdm dbus hal dhcdbd networkmanager autofs keytouchd)
and my modules are
MODULES=(b44 mii acpi_cpufreq cpufreq_stats cpufreq_powersave cpufreq_conservative cpufreq_ondemand cpufreq_userspace ipw2200 ac97_bus snd-mixer-oss snd-pcm-oss snd-page-alloc snd-pcm snd-timer snd snd-ac97-codec snd-intel8x0 snd-intel8x0m soundcore i8k)
I don't think I've configured enough files or something like that.  Are there any files in /etc/ that I should be modding to get suspend to ram to work properly?  Is there anything wrong with my daemons or modules? 
Thanks in advance for any help you can give,

I've got suspend and hibernate to work with pm-utils (and kpowersave-devel) on a Dell Inspiron 6400 about 80% of the way, and I'm appending my install notes on this.  Perhaps they'll help you.  This new power management scheme looks like a convoluted mess to me, and I'm still flailing with it.

--- How to configure Arch for power management on Dell Inspiron 6400 ---
1. Install acpid, pm-utils and cpufrequtils, i.e. # pacman -S acpid pm-utils cpufrequtils
Add 'acpid' to the list of DAEMONS in /etc/rc.conf.  If you already have hal specified in your DAEMONS, there is no need to add acpid. HAL will automatically detect and load the acpid daemon.
Both pm-suspend (suspend2ram, low power state) and pm-hibernate (suspend2disk, system powered down completely) are usually called from HAL, e.g. initiated by the desktop applet kpowersave.
They can be run in several ways:
a. Via buttons or shortcuts (e.g. Fn-ESC for Standby, Fn-F1 for Hibernate)
b. From KPowersave in task bar
c. Or, without using HAL and other frameworks, call pm-suspend or pm-hibernate from the command line as root:
# pm-suspend
# pm-hibernate
2. Configure pm-hibernate (suspend2disk):
When the machine is placed into hibernation, it will move all data from RAM to the swap partition (swap size must be >= RAM).  Edit the kernel line in /boot/grub/menu.lst by adding 'resume=path_to_swap_partition', e.g.
kernel /boot/vmlinuz26 root=/dev/sda2 resume=/dev/sda5 ro vga=791
3. Configure cpufrequtils:
a. Add the driver "acpi-cpufreq" to the MODULES list in /etc/rc.conf.
b. Load a governor(s) (a pre-configured power scheme, loaded as a kernel module) by adding 'cpufreq_ondemand' or 'cpufreq_powersave' etc. to the MODULES list in /etc/rc.conf.
c. Edit /etc/conf.d/cpufreq to include valid governor(s) and the proper freqs for your CPU (get these values by running $ cpufreq-info), e.g.
governor="ondemand"
min_freq="1GHz"
max_freq="1.67GHz"
d. Add 'cpufreq' to the list of DAEMONs in /etc/rc.conf (after 'hal').
e. In /etc/pm/config.d/ create a file 'config' and in it list the modules to be unloaded before suspend, e.g.
SUSPEND_MODULES=" button uhci_hcd"
5. If applicable, change the labels for the power and sleep buttons in /etc/acpi/handler.sh.
E.g. in Dell Inspiron 6400 replace PWRF with PBTN and replace SLPB with SBTN.
6. Configure proper handling of lid closure by editing the button/lid section in etc/acpi/handler.sh.
I don't know how to do that as yet but the following hack at least will allow you to close the lid after putting the laptop on Standby and have the screen come back to life after resuming, rather than having it remain black.
Put the following shell script '000hacks' into /etc/pm/sleep.d/ and make it executable (you'll have to install vbetool):
#!/bin/bash
case $1 in
    suspend)
        chvt 1
        vbetool vbestate save > /tmp/vbe
    resume)
        vbetool post
        vbetool vbestate restore < /tmp/vbe
        chvt 7
esac
