> 1) The kernel radeon framebuffer driver doesn't mess with

They leave alone the swapper of the engine, not the fb one
(SURFACE_CNTL) afaik.

I dbl checked the other day and it seems that we setup the GART before
we whack it tho but it might be an issue in conjunction with radeonfb
(ie, I don't have radeonfb on my test embedded boards as I rely on X to
POST the cards using ATOMBIOS).

Cheers,
Ben.
