I just noticed that I seem to be having a problem with my cardbus which I
think might be related to your pci changes.  I haven't completely dug through
the cvs logs though, so I might have missed something :-)

 | pci0:3:3: setting power state D3
 | pci0: Failed to set ACPI power state D3 on (null): AE_BAD_PARAMETER

This shows up on a number of devices and is probably related to whatever the
author of my bios was smoking when he was writing it.  I'll read through my
acpi tables and see what I can come up with.

I have no idea what all this is supposed to mean :-)  Anything I can do to
help sort it out?

Works well here.  My laptop suspends/resumes almost completely happily now.
Yay :-)
