Looks like you're missing the xserver-xorg-video-ati package, which is
necessary for the radeon driver to get loaded automagically by the X
server. Maybe this package was accidentally uninstalled along with the
libc6 upgrade?
If you can't or don't want to install it again for some reason, you can
explicitly choose the radeon driver in xorg.conf Section "Device".

Does commenting out this SubSection "Display" (or moving xorg.conf out
of the way altogether, it shouldn't be necessary anymore) help? It's no
longer needed with the radeon driver with KMS, and I suspect it's
triggering bugs with the fbdev driver.
