..run 'dpkg-reconfigure locales' and pick or verify you have picked
all your relevant UTF-8 locales, you may want to toss out your
"ISO-8859-*" locales. Next, run aptitude and trawl 'n haul in
"all" UTF-8 fonts, and make those your apps, wm, DE etc defaults.

..and 'xrandr --verbose' says?
..also chk KMS, http://www.google.com/search?q=Debian+radeon+KMS
is a good starting point, http://wiki.debian.org/KernelModesetting
and will be set by default in /etc/modprobe.d/radeon-kms.conf:
"options radeon modeset=1"
..chk the other ones (/etc/modprobe.d/*.conf) too for conflicting
configs or fb etc drivers that should have been blacklisted.
..also chk bug reports, a fix is probably on its way, I saw mention
of "linux-3.1 not working with radeon."
..I had a vaguely similar issue a coupla years back that I fixed
making new and slightly slower modelines, I was pushing my card
too hard and got white flickering, but only in FlightGear.
FG is fairly tough on graphics hw and may help diagnose it.

Scenarios always come in sets of three:
best case, worst case, and just in case.
