Hm. Dumping oops information plus perhaps even a memory dump to a USB
key sounds like it would be highly useful - lots of storage capacity,
readily available, and can be plugged into just about any system.

I don't know if the backdoor debugging mode in EHCI can be used for
that. Either way, this would have to be done *very* carefully to avoid
clobbering USB devices not intended for this purpose.
