hardware limitation, not a bug. The GPU can use the whole VRAM, so you
don't need to worry.

Well, reading that mentioned post at phoronix again and again, where does this
limitation come from?
Is it caused by ther kernel or do I missunderstand it .. plx
If it's not harware limitation, then it is in fact a bug. Maybe a

I'm having the exact same problem with my Radeon HD 3650. Only 256MB of
the 512MB are detected according to Xorg.0.log. Apparently other linux
users have the problem too - here's a Phoronix thread that talks about
possible work around:

It's independent of fglrx.

the radeon driver detects 512MB but say, that only 256 mb are accessable...

I can confirm this. Using hardy amd64 with fglrx 8.6. lscpi does not
detect it correct, too. I have a Sapphire Radeon HD 3650 with 512 MB
GDDR3.
