This file must be an Ubuntu-ism, because neither that file nor that
directory exist on my Debian box.

Yeah, I tried those as well. I dumped a webpage about sysrq into my docs
directory, so I'd have it. But it doesn't appear to work. However, I
haven't checked to see if sysrq is enabled on her box.
I checked, and on my box at least (don't know about Nancy's)
Ctrl-Alt-Bksp is disabled. I kept hitting that combination accidentally
and killing the X server. How can you possibly "accidentally" hit that
key combination? Ask my fingers. ;-}
