It is a Sapphire X1900 crossfire edition card, that has 512MB of memory:

At the end of March I could use only text installer in rawhide because both vesa and radeon drivers failed to load.
With latest updates ( anaconda-11.4.0.71-1 ) radeon driver is successfully used and loads during installation. Well!
In the system, after install, I see this in my Xorg log:
(II) RADEON(0): Detected total video RAM=524288K, accessible=262144K (PCI BAR=262144K)
(--) RADEON(0): Mapped VideoRAM: 262144 kByte (64 bit DDR SDRAM)
So it seems I only use half the available memory, correct?
How to get rid of this problem, in case?
I'm using EXA accel method because it is the only one that allows xvideo with radeon driver.
And it seems stable, at least on my configuration, but it is not the default one at the moment...
