May I ask, what trouble?

I can suspend to disk (Fn-sleepbutton, so via BIOS, to a preallocated
file on 'C:') on the Armada 1500c, and sometimes do to preserve state
over a few days, but suspend to RAM is very much faster, startup < 10s
even with a Celeron 300 (albeit only 160MB RAM).  Also, suspend to disk
on hitting critical battery low can be a bit hit or miss.

I don't mind if only APM works, if it does, but finer power control
would be nice (again towards running on battery for lengthy periods),
with quite a few browser windows, edit and console sessions on the go,
very seldom rebooting.

Thanks,
