Excerpt from /var/log/syslog for 2.6.36.1

The above gets logged now to syslog when the lockup happens (the "couldn't
schedule IB(…)" part continues endlessly (until I killed KDM) after the line I
cut off, but I thought one iteration is enough). Unfortunately I deleted the
rescued Xorg.0.log which had additional information. From what I can remember:
it looked like what Eric posted in comment #12, though I had two backtraces
there, one over the line "(II) AIGLX: Suspending AIGLX clients for VT switch",
which was about 20 to 30 lines long and then something that was like the part
posted in comment #12.

The software versions used are:
Kernel: 2.6.36.1
DDX: 6.13.2
Mesa: 7.9
libdrm2: 2.4.22
