Is any of this relevant?
I had similar sorts of trouble with an X22 + Ultrabase last year.

Also, if you boot the system in single user mode (append "single" to the 
kernel command line), it should make the boot-test-crash-reboot cycle a 
little faster.

Lastly, it's possible (though I don't know how) to do memory dumps by 
using a fire wire card.

Best wishes,
