Card is an AGP RV670. libdrm,mesa,ddx and xorg are current gits.

After the recent batch of commits to drm-radeon-testing I have a perf 

It doesn't show immediately, but after running a timedemo on nexuiz 
followed by openarena, further timedemos on either will have very poor 
performance - 4 fps and gears may be as low as 100fps.

Nothing in dmesg during bisect (though I saw a few errors when on head - 
I think they are a separate issue) and free looks OK.

Once this has happened 2D performance is also reduced a bit - menues on 
seamonkey slower than before and when displaying a page with a second 
counter, sometimes all rendering will glitch briefly every second - can 
be seen just with key repeat in an xterm.

Git bisect came up with -
