The intermediate status:  I installed Debian Squeeze on an extra disk, and there the radeon driver works when I add the 'Option "MacModel" "mini-internal"' to xorg.conf.  Not a big surprise, as Linux 2.6.32 is rather old.  I also included 'radeon.modeset=1' in the Kernel command line.  dmesg says '[drm] radeon kernel modesetting enabled', but Xorg.0.log warns '[KMS] drm report modesetting isn't supported.'.  Hmmm....

Without an xorg.conf file (i.e. w/o the mini-internal option), I see the same shades etc. I reported for Ubuntu 12.10 with the 3.7 kernel.

I will try the next available kernel versions (2.6.34, 3.0, ...) so I can narrow down the point where it fails (hope this is the right approach?).  Unfortunately, building the kernel takes ages...
