Sometimes the graphics card is locked up, but the cpu is still running;
it is just that you can't see what it is doing.
If the Xserver is chewing cycles you might not have a keyboard either.
In these cases, syncing the disk can flush buffers so that the
log file does contain useful info on reboot.

You did redirect stdin *and* stderr ( >& in bash) to the logfile ?
I can't remember now, does XF_SVGA have options to increase
its verbosity ?
