Do you have a backtrace for this crash? (either at the end of the log,
or (better) with gdb)

Is it actually a freeze? Or just the server not restoring the VT console
because it crashes before doing so (known bug in Xserver 1.4)?

Please try with Xserver 1.4 anyway. You're reporting a bug against a
package which has never been in Debian so far :/

You should try removing all these options.

You should try EXA instead of XAA too (especially with Xserver 1.4).
