Please try to extract a stack trace yourself out of gdb. I don't have 
your X server binary...

Usually X crashes on resume on the X40 because the graphics engines 
locks up. The X server detects it and tries to exit cleanly, but 
sometimes fails.

This has been identified by Alan Houriane, the main developper of the 
i810 driver by a race problem between the APM BIOS that tells the OS 
that the machine just woke up and the video BIOS which has not 
completely restored the graphics chip set. He mentionned ACPI as a 
possible way to "fix" that, but I think OpenBSD is far from having ACPI 
suspend/resume support.
