I tried disabling, one at a time. Results are not very useful, I fear:

1 Disabling R600PrepareCopy resulted in slow FF scrolling

2 Disabling R600PrepareSolid: Xorg freeze

3 Disabling R600UploadToScreenCS: Xorg freeze

4 Disabling R600DownloadFromScreenCS: Xorg freeze

5 Disabling R600PrepareComposite: no freeze, just slow scrolling. I tried it
for ~20 minutes, methods 2, 3, 4 crashed after <5 minutes.

The funny thing is, that I got no "Failed to parse relocation" dmesg errors.
Maybe debian/ubuntu isn't using the git tag xf86-video-ati-6.13.0 as I did in
these tests...
