Yes.  One more difference: the board I'm testing is bare naked,
sitting on a non-conductive surface.  The parts I'm swapping in and
out are in an Apple resting comfortably in a case.  Grounding, maybe?

Yep, that looks like the problem.  I buttoned everything back up, and
now things are looking much better.  Disks are booting, and the
keyboard is decidedly less flaky than before.  Still flaky, to be sure
- but that's the nature of this particular beast.

Then there is something very marginal going on.  You might want to
take it back out of the case to make it easier to find.
