Ok, this actually works now. Not only does it work, but it works fairly
damn well. With a workaround, I can even recover from S3 with the
buggy firmware on my Latitude D600. I'm still working through a few
device driver issues (iwi completely loses on resume, for example), but
I'm happy with the state of this support. Make sure you grab the
20060309 patchset; the 20060307 patchset is useless.
PLEASE TEST THIS CODE! It's very simple, boot a kernel with these
patches single-user, and run 'apm -d -z'. Report your results. If you
can, provide patches to hardware device driver powerhooks. This is
probably the biggest task involved with getting ACPI suspend/resume
 If your firmware is broken and doesn't re-initialize the display
adapter on resume from S3, try setting a power-on password in your BIOS.
The 'enter your unlock password' screen is enough to kick mine back into
