Network-crashing problem

Question

Hi
I've got problem with my network connection. I've been looking through arch forum, wiki, google, but usually people have slightly different problem. Some of my config files:
/etc/rc.conf
MOD_AUTOLOAD="yes"
MOD_BLACKLIST=()
MODULES=(p4-clockmod cpufreq-ondemand fglrx 8139cp 8139too mii bcm43xx ac97_bus snd-mixer-oss snd-pcm-oss snd-page-alloc snd-pcm snd-timer snd snd-ac97-codec snd-atiixp-modem snd-atiixp soundcore)
HOSTNAME="marcin-laptop"
lo="lo 127.0.0.1"
eth0="dhcp"
eth1="192.168.0.2 netmask 255.255.255.0 broadcast 192.168.0.1" # that's my wifi, but now it's irrelevant
INTERFACES=(lo !eth0 !eth1)
gateway="default gw 192.168.0.1"
ROUTES=(!gateway)
DAEMONS=(syslog-ng acpid cpufreq dhcdbd networkmanager !network !netfs crond hal fam ifplugd @openntpd @alsa @mpd !entranced)
/etc/hosts
127.0.0.1 marcin-laptop.domain.org localhost.localdomain localhost marcin-laptop
#127.0.0.1 marcin-laptop.localdomain localhost marcin-laptop
/boot/grub/menu.lst
# (0) Arch Linux
title Arch Linux
root (hd0,6)
kernel /vmlinuz26 root=/dev/sda9 irqpoll vga=773 ro
initrd /kernel26.img
Configured as above, my connection crashes after a while (but just after booting it's OK, "while" is ranging from circa 3 minutes to about 1 hour); restarting eth0 and dhcdbd makes it working again. What's more, it works perfectly with "noapic" kernel option, but I can't use it due to problems with HD (noapic makes my disk slower by 70-80 per cent, I have written a post about it some time ago).
I started changing some random options, but it hasn't brought any positive results - I've tried to disable 8139cp module, INTERFACES=(lo eth0 !eth1), using 'network' - not 'networkmanager', running kernel with other options (pnpbios=off, pnpacpi=off, pci=usepirqmask, any combination of them), changing lines in /etc/hosts - shortly, I've tried every even far-networking-related solution I could have found on Internet.
Have you got any idea, what the problem is?
P.S. Under Windows works with no problems.

I recently started experiencing network problems... I'd say over the past two months.
I used to have a lot of issues with my ISP, so I just wrote it off as them having problems again. But, lately that is not the case. My modem stays completely connected while my connection in arch drops. What really made it apparent was when I had a friend over. He was using internet same time I was and viola, mine got disconnected, his computer was still working.
So even though I do not know what the issue is currently... I will convey I am having same problem. Could this be an arch package problem? Or is this a quark in the code?
