From what I remembered from Phoronix.com and elsewhere, Squeeze is to old
for HD6xxx series. man radeon might give a hint as it usual contains a
list of supported cards.

What does xrandr display? The mode related stuff from /var/log/Xorg.0.log
might also help.

Are you sure about that? Did you try? What does apt-cache show xserver-
xorg-video-radeon give for the backported one?
I ask cause 6.13.1 and 6.14.2 does not seem much of a difference regarding
the version and it should be possible to mix versions to a certain degree.

I don´t think its a problem, but you only know for sure, when you try it.
Although downgrades are not officially supported, I did those several times
with X server packages and they generally worked well.
I have a ThinkPad T42 where the Wheezy driver (not the most current one,
but I think nonetheless a 6.14 one works well. But thats with a rather old
card. I would have to look the exact version up as the T520 I am using now
has Intel Sandybridge graphics.
