Yep, problems with the radeon driver's fallback behavior when
microcode is not available are not so unusual. :/  Still, provoking
random segfaults is not great.  I guess what would be most useful is
(1) to try a recent (3.x) kernel from sid or experimental, (2) to
build from source, enabling some debugging options from the "kernel
hacking" section in "make menuconfig", and then (3) to report this
upstream with a patch.

I can help with (2) and (3), but I cannot promise to be quick at
all.

For now, please attach output from

	/usr/share/bug/linux-image-$(uname -r)/script 3>&1

so we can tell what hardware and drivers you are using, then try a
kernel from sid or experimental if you have time (you'll also need the
linux-base and initramfs-tools packages from sid or
squeeze-backports).

Thanks for a pleasant report, and sorry for the delay,
Jonathan
