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 report's state I assumed that the patches
would be applied to the upstream kernel, but I have not found a trace of
them in 2.6.34-rc5 yet. The lspci information for the video card is
identical to "dell studio 15" information, except that the IRQ is
different. I have not tried the actual patch, but as it seems to set the
new_pll setting to legacy for my video card I'm assuming it would fix
the problem.
