No. Quirks currently exist to work around missing functionality. Once 
that functionality is implemented, continuing to provide the quirks is 
working around bugs. It's more important to find and fix those bugs than 
it is to band-aid around them. On KMS systems, they're actively damaging 
- the kernel will program graphics mode, the quirks will program text 
mode, X will ask the kernel what mode it's in, get the wrong answer 
(because the kernel still thinks it's in graphics mode) and then attempt 
to display on a card that's set up in text mode.
