Unknown "mem" state issue

[Petros Kolyvas <pkolyvas-Re5JQEeQqe8AvxtiuMwx3w@public.gmane.org>]

Hi!

I can't seem to send my system into the "mem" state. I've recently
switched from FC4 to Gentoo. My kernel is 2.6.13-r3 with some custom
patches - including the new ieee802.11 subsystem (ieee80211.sf.net) for
the linux ipw2200 drivers (ipw2200.sf.net) patched directly into the
kernel (which may very well be part of the problem) - but I was unable
to suspend to memory before such patching occurred. acpid is 1.0.4-r2
and I did compile the acpi kernel options, including the userspace
governor for my cpu into the kernel and I am using powernowd to to
manage my CPUs frequency settings.

Basically my tried and true acpi sleep state script hasn't been working
and even when I manually 'echo "mem" > /sys/power/state' the system
doesn't respond at all.

I'm not sure where to start or what I'm doing wrong.

Thanks for your time and consideration.

Petros
