Afaik it is already possible to distinguish systems by their video card and 
used driver within the hal whitelist. But it case there are several video 
cards installed, it is not possible to apply  differents quirks to different 
video cards. But this is also a limitation of some quirks, e.g.

<match key="/org/freedesktop/Hal/devices/pci_10de_322:info.linux.driver" 

is recognized on my desktop that uses an nvidia video card with the binary 
driver. In general, it should be possible to match agains anything that is 
stored in hal, I used lshal to find out what I can use to match agains my 
video card.
