Guess what, I have received a new USB key today, and it shows the problem
right off the bat. But what's more, my old and trusty SDDR-31 now misbehaved,
too (only one time though)! Here's an unedited dmesg:

Insanity! I guess I'm too cheap to buy good stuff which breaks, Jamie :-)
The 1GB key was sent to me by Red Hat (the laptop, too). Hurray for corporate
support.

I'll let you know if I find and fix this, but it's likely the same problem.
