I installed now newest (git, cvs) versions of Xserver, Mesa and DRI.
Quake 2 is as slow as before. glxgears is down to 1/3 of its old speed,
but Nexuiz doesn't give an error message anymore and feels smooth from
short testing.

googleearth works now too, but speed is only acceptable, if I redirect
stdout to /dev/null, as I get _lots_ of lines like

0x0 0x0 0xbf

This also happens with another program, but I think this is more likely
to be a Mesa problem.
