Did you perhaps upgrade your kernel?  xfree86 4.3.0.dfsg.1-8 hit sid about
28 September, quite a while before your dist-upgrade on 29 October.

Very odd.

Does the debugging X server, in the package xserver-xfree86-dbg, work?

Failing that, can you install strace, log in remotely, and launch the X
server (as root) from strace?

Hopefully we'd get some sort of idea what system call is being issued
shortly before the lockup.  And by logging in remotely you should be able
to capture the strace output.
