Testing with rv790 with drm-fixes kernel not much works -

etqw runs but in a level 50% of screen is junk.

nexuiz menus total junk, didn't test further.

xonotic menus OK but gpu lock on starting timedemo.

vdpau mpeg2 decode - renders 90% junk.

heaven 3.0 (on a different pure 64 bit setup) gpu lock.

Unrelated question wtr heaven 3.0 - does it work properly anyway?

For me running 64bit on rv790 with vanilla mesa with or without llvm I 
have to set shaders to medium, on high it works but I get no 
lighting/effects. There are also a couple of scenes that render as 
flared out black and white.
