No.  Sorry, I should have mentioned that - that's one of the things I
tried.

Beep from the keyboard?  No.  Hm, I'm not sure I do from the 5, either,
though the beeper in the keyboard works.  I'll have to experiment.  I
do get the two faint beeps from the LX itself, same as always.

What lights?

It's not a problem with keyboard power.  First, the keyboard works for
input when I use ttya for output with "input-device=keyboard!"; second,
the visible LED on the mouse is lit.

In general, the PROM doesn't recognize keyboard presence if it can't
send it something and get something back.  This is why I suspected a
dead input or output driver (ie, failed in transit, because they both
worked when I had it at home), but input definitely works, and output
works enough to get the keyboard to send a reset ack and type byte.

Hm, worth checking.  I'll have to look into that - while it would be
the only case I know of where a more-modern machine can't handle a
type-3, it's true Sun has left some surprising idiocies in some of
their ROM versions.
