[ltp] Suspend not working w 2.6-test5-mm4

[Antiphon]

I've upgraded all my desktops to 2.6-test5-mm4 w/o hitch but my 600X is 
causing me trouble. Under 2.4.20, the machine will suspend properly but not 
under 2.6.

I'm using Debian sid in case that helps any. Is there some package I need to 
upgrade in order to get APM to work properly? I don't know about ACPI since I 
can't make any major changes in the BIOS for some reason :-( Right now, it's 
disabled.

Anyone else encountered suspend problems w/2.6?
