Suspend on a thinkpad R32

[Brian Perkins]

So I tried core 1, which seems to work about as well as RH9 with my 
R32.  I' have a few outstanding issues.

1) The APM BIOS stinks with battstat.  Unfortunately polling the battery 
(which battsat does once per second) via the APM bios seems to cause 
keyboard interrupts to get dropped, which is veryyyyyyyyyy annoying.

2) Whenever my linksys WPC11 PCMCIA card is plugged in and the AC power 
is plugged in, the machine refuses to sleep (rather, it almost always 
refuses to sleep).  It does suspend if AC is unplugged and the PCMCIA 
card is plugged in, but this seems kind of dumb and it crashes about 10% 
of the time.

It starts up the fan like it's about to suspend, but the suspend never 
actually happens, and it makes a beeping noise.  I've seen the same 
behavior with the orinoco_cs driver and the wlan-ng driver with RH9. 

3) ACPI used to be very buggy and now very nearly works, but I get the 
exact same refusing to suspend behavior, but this time regardless of AC 
or PCMCIA cards plugged in or not.  I've tried disabling PCMCIA 
altoghther with no luck.

To get around the #2 problem, I tried to have apmd unload the network 
driver before it suspends, but it appears it gets stuck even before it 
notifies to apmd.

I'm also a bit confused as to why suspend is doing anything at all.  I 
looked at acpi-devel and read that the S3 state isn't supposed to work 
at all under 2.4.  Is Fedora using some sort of unholy marriage of apm 
and acpi when acpi is enabled?

At this point, I'm not sure exactly what to blame. I assume that the APM 
BIOS is buggy, and ACPI is really my only hope.
 
Can anyone suggest a way to track this nonsense down?

Just for kicks I tried 2.6-test9 (kudos to whoever updated modutils to 
make this a reasonable endevor)  which behaves differently, and will 
suspend and come back (though it appears that the uhci driver is totally 
trashed).  Maybe there's some hope there.

Sorry for the sort of rambling post.  I've been playing around with 
these issues for a few months now.
