Not sure if this applies because I've a "MS" version. But maybe this wil
yield a clue?

When I hook it up and use it, in a VT, there are some extra codes
emitted that spawns a message saying the code is unrecognized and I
should setkyecodes to fix it. In my case the code is 0xe001.

These same messages would appear under X in a terminal.

This fixed it for me.

# cat bin/FixKb
#!/bin/bash
setkeycodes 0xe001 1

My thinking is that to conserve battery, or account for a
sleeping/hibernating system, this code is emitted as a "wake up".

Anyway, my suggestion is that some review of some man pages might
provide the real solution.

dumpkeys
loadkeys
showkey
getkeycodes
setkeycodes

There might be a couple I forgot, but some of those, IIRC, have layouts
defined. Maybe one of them fixes your issue.
