I guess the question is, is this chunk of code actually doing anything
useful/important, or is it just there to support DGA on VESA?  If the
latter then people who don't need/want DGA (which is probably everybody,
nowadays) can just take it out.

All that said, I would have thought that the VESA driver itself was
pretty much a fringe interest in this day and age.  Is anybody really
using that on a shipping system?  If it's just for qemux86 test harness
purposes then maybe we could turn on the vesafb driver in the kernel and
use the straight framebuffer driver in Xorg rather than the VESA one.

I don't think it's that self-contained.  Admittedly it isn't all that
big either, but still.

I don't quite understand what xrandr has to do with that.  How does this
relate to DGA?
