Attached is the code I posted to the hal mailing list last November to
migrate the video quirk database out of HAL and into something a little
easier for bash to deal with.  It did not have the full expressive power
of the hal-info XML format, but that was mostly not needed anyways --
the only place it was used was the 21-nvidia quirk for handling g80
chipsets with the nv driver, but that can just as easily be hacked into
a few lines of bash.

Hacking this into a pm-utils hook would not be that tricky -- the flow
would go something like this:

if has_kms || has_nvidia || has_fglrx || has_smart_intel; then
	skip_all_quirks
elif has_nvidia_g80; then
	do_g80_magic
else
	use_video_quirks
fi 

video_quirks definitly has bugs, but it did OK as a proof of concept for
me.
