OK, here's the gdb output and then my explanations:
====================================================
Continuing.

#4  0x00000000 in ?? ()

====================================================

Explanations:
1. I recompiled X and x11-drivers with the debug USE flag, but it looks like a
lot is still missing. I'm not sure which.
2. I tried following your scenario, ie- attaching gdb to X when it hangs, but
as I expected, gdb fails to attach. So instead I attached gdb before the X hang
and then switched vt's to hang.
3. I had to use ctrl+c in order to make gdb stop and give me a prompt.
4. I used the original configuration- ie including DRI.

That's it.
If there's anything I can do better just let me know.

Doron.
