Hrm, I don't normally use kde, but I have tested with it at times.
Normally I use compiz+gnome and performance should be more than
acceptable. Even games like nexuiz, openarena, UT and vdrift should be
well into the playable range now.

Actually, I don't see anything odd in this config. The only thing I can
point out is that I use the radeon driver rather than radeonhd, but it
isn't clear to me if that could somehow impact performance in this area.
The only reason that I know of to use radeonhd currently is if you need
HDMI audio, otherwise radeon has everything and more.
What kernel are you running on? Any -CURRENT or -STABLE branch should
have all the needed bits. If you have a kernel that doesn't have
r600_blit.c then it will be really slow since the initial code used a
memcpy before the hardware support was enabled.
