Neil Brosnan suggested it was likely the new kernel patch, 105181-17.
After backing it out, everything works again, so it does indeed appear to
be the culprit. *Don't* install 105181-17, or back it out if you already
have, as it obviously has some nasty bugs. (Neil was getting other crashes
until he backed it out.)

Bruce Cheng mentioned patch 105362-22, (the M64 Graphics Patch) which isn't
part of the recommended patch set. Not having it installed can indeed
cause crashes, but I had installed it in July.
