The 7.2 -intel update adds patch 121_fdo-28798-fix.patch.  This patch
significantly changes rendering behavior with 2D graphics acceleration,
thus is definitely a strong suspect for this issue (although it's quite
strange that it affects the console too!)  To prove it is the patch's
fault, downgrade to 7.1; if it no longer reproduces within ~1 day, then
the patch is at fault and we should not proceed with the SRU.  If it
still reproduces, then we should examine dpkg.log for other possible
suspects.

Corruption that affects the console indicates either a kernel bug, or an
X bug that somehow put the GPU into a really bad state.  Booting and
reproducing on an earlier kernel would rule out it being due to a kernel
update.

If it *is* pinpointed to the patch, would you mind also booting an
oneiric livecd and see whether you can reproduce it there.  I ask
because we're already including this patch in oneiric and if the same
issue exists there, we ought to look into it more closely.  If it
doesn't occur on oneiric, then presumably we can just forgo the 7.2 SRU
and leave it at that.
