I recently migrated to radeon/radeonHD on my two computers and I had these
problems too. I had past experiences with EXA breaking things and so I thought
I could have a look at xorg.conf/exa man pages. I found those two options
Option  "EXAOptimizeMigration" "on"
Option  "MigrationHeuristic" "smart"
to enable in the Device section of xorg.conf. Defaults are off/always. Possible
values for MigrationHeuristic are always/greedy/smart. I haven't tested greedy,
but with this combination I'm having a very smooth desktop experience.
With glxgears, rendering rate moved from ~400fps to ~3100 fps (X1900
XT(R5xx)/radeonHD). I had same problems on my laptop (9600Pro(R3xx)/radeon),
glxgears comparison is ~200fps against current ~1000 fps. See "man exa" for
more details.
I'm using xorg-server 1.5.2 + radeonHD 1.2.3 (git). DRI enabled in both cases.
