Certainly a silly question, but does it mean radeonhd driver won't be able to
support more than 256MB of vram or is it just a restriction of the 2D mode of
the videocard because of the bus or something ? 
Otherwise does it apply to the 3D mode  too ?

If only half of the 512MB of vram is mappable I will instead consider buying  a
256MB only radeonhd videocard  in the near future with the benefit to consume
less power :)

I really appreciate your work. The driver is rock stable. It is fast enough for
a commun use with the shadow framebuffer mode activated and the videocard is
still silent. I'm really eager to test compiz-fusion with the upcoming
accelerated driver as soon as it will be available for testing.
