I had not noticed that the code still implied a dependence upon the XAA
module.

It does. The mapping of the ring and control registers was already
managed outside of the XAA specific routines, so enabling the blit
function without the XAA infrastructure is fine.

Tested insofar as running glxgears on a remote i815 with XAA exorcised.
Not totally convinced I've verified all the necessary paths, but it
loads and seems to run.
