The problem is that the quirks as they are currently implemented have no
provision at all for handling the case where you can purchase a single
model of system with multiple different types of graphics cards.

I think it is rather ironic that the video quirks in HAL assume that any
given system model uses only one type of video card.  This is assuredly
not the case for a significant amount of modern hardware, and is
woefully inadequate if we want suspend/resume to work at all reliably
out of the box for desktop hardware.
