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.
