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.
