I'm going to try to get this PC put back into co-lo where it can

INVARIANTS and INVARIANT_SUPPORT to the PAE-based configuration, and
it panic'd during startup, either during fsck of the root filesystem
(if multi-user startup) or immediately after I pressed return
Um, help? Pretty please? My clues about this part of the kernel are
a bit stale. I don't know how long I have to play, and don't think I
