Wireless not working after suspend (madwifi)

Question

Hi there
I successfully converted from Vista to Archlinux! Everything's working fine (yep, I'm a bit proud as this my second try at linux ) except that after I suspend with powersave my wlan is not working anymore. I've also tried to unload the ath_pci module and restart the network in /etc/powersave/sleep but that doesn't seem to work.
I guess it has something to do with the network deamon because when I try to restart my network manually it says that dhcpcd is already running for ath0... Oh, and also the iwconfig for ath0 seems to be perfectly correct after suspend...
Here's the network part of my rc.conf:
lo="lo 127.0.0.1"
eth0="dhcp"
ath0="dhcp"
wlan_ath0="ath0 essid FeelGood key s:******"
WLAN_INTERFACES=(ath0)
INTERFACES=(lo !eth0 ath0)
Any ideas? Help would be appreciated

Well, maybe you already know this, but: ath_pci (the madwifi driver) is among blacklisted modules (/etc/hibernate/blacklisted-modules), so it gets unloaded during the suspend process. That screws up whatever wireless connection you might have had before suspending. Now if you have the option LoadModules auto in /etc/hibernate/common.conf, it should get loaded after resuming - but that of course doesn't renew the connection. So that I do is I have a short script that calls /etc/rc.d/network restart, and I run it manually after suspending to renew the connections.
BTW, I have this in /etc/hibernate/common.conf:
UnloadBlacklistedModules yes
LoadModules auto
EDIT: Eh, B managed to post before I finished writing this :)
