Description Allan Saddi 2000-04-22 18:50:02 UTC 
On my Compaq Presario 1215, the timer-based suspend/standby requests
from BIOS interfere with normal APM operation. For example, when I use
'zzz' to suspend, my laptop will wake up on its own after 15 minutes
due to a BIOS request. (I can only assume it's attempting a suspend-to-
disk operation, which I really haven't gotten to work yet.)

I cannot disable these requests from BIOS setup, hence this patch. I am
using device flag 0x40, which does not appear to be used, to signify
that BIOS timer requests should be disabled from apm_attach().

How-To-Repeat: 
Suspend using 'zzz' when on battery power. Wait 15 minutes.

Please close this PR for now. After more extensive testing, I've found
that it doesn't quite fix the problem.
