After finding http://bugs.freedesktop.org/show_bug.cgi?id=26358 I found
out that new_pll=0 as radeon module parameter seems to fix the
problem. That is, I've been running with it for multiple days and have
not yet reproduced the flickering behaviour I had before.
Given the (freedesktop) bug
I've done more experimenting regarding this issue.
With the patch and disp_priority=2 module parameter the glitching is
significantly reduced (though not completely). It makes my computer more
usable.
2.6.34-rc5 with disp_priority=2 is (much) worse than
2.6.32-4_2.6.32-10 (with patch),
The new 2.6.32-11 exhibits the same flickering behaviour as 2.6.32-10.
With the application Eclipse running in the foreground the flickering
is unbearable with 2.6.32-11 and 2.6.32-10 with the patch from
http://marc.info/?l=dri-develm=126996657723896w=2 (I have not tested
the unpatched version
I've been a little bit premature about cheering it was fixed.
It occurs much more rarely, but it occasionally happens. I've had three
occurrences in 8 hours of use (instead of 3 or so a minute). One time a
cronjob just started updatedb, the other times I could not find any busy
application.

Yes, applying that (manually because some chunks fail to apply) to the
kernel's source package seems to fix the issue. Thanks you!
So it seems the problem is in the kernel and not the
