Well, having stumped all the experts, I decided to reinstall from
7.0-BETA3 CD-ROM.  After a few minutes of writing to the disk after
newfs, I got more panic: ffs_clusteralloc: map mismatch errors.  Since
the device I'm writing to is a 3-day old Maxtor OneTouch III external
HD, I've decided it must be a hardware failure and am returing the
drive.
