I think it should be possible, but you need to make sure to use EXA
instead of XAA and that you use something close to current upstream Git
- xserver-xorg-video-ati from experimental may or may not fit the bill.

If this advice doesn't help, please provide the full xorg.conf and
Xorg.0.log corresponding to it.
