Hard for me to test fglrx on my setup, but soon I should have more ram to play
with.

The recent changes to to agd5f 3.19-wip seem to have provoked a new issue -
haven't had time to find a commit yet.

Will attach a screen showing that near the end of the demo there is a new
really long pause (graph doesn't really show length, but it was around 10 sec)
that corresponds to a big move from vram to gtt.

Other demos eg. valley don't show any issues and run well.

IIRC there is already a bug somewhere about the rendering issue (common to most
unreal demos) that makes part of the logo black in the screen shot.
