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.
