Several of you reminded me of the question on this list's FAQ
on Quantom drives. Indeed, giving this one a twist freed the
drive and the system is now booted. Thanks!
Other suggestions involved various combinations of booting from
tape or CD-ROM, mounting the "root" partition from the drive
temporarily and re-running installboot(8), or running format
from the miniroot. These are great suggestions when the drive
in question is spinning, but in my case the drive had not spun
up due to the "stiction" problem.
