Only one example where it breaks for me one machine: Dell XPS M1330 (Intel 
GM965/GL960) break without quirks and i915 kernel driver (kernel version 
2.6.24 and 2.6.25-rc5-git3). This machine obviously need quirks which isn't 
possible with your patch since there is _no_ way to overwrite the case that a 
machine with Intel/Nvidia/fglrx still needs special quirks to run. I assume 
this is only one of potentially many cases.

So your patch would break still working machines.
