Yeah.  That's why I specified that this is a _cheap_ switchbox...
I just re-checked with 1.4.1 on one of my systems.  It probes OK, but I
get at least one

	pckbcintr: no dev for slot 1

for each keypress after it comes up (and, unsurprisingly ;-), the
keystrokes are not registered as keystrokes at that point).

Hmmm...  Looking at it, it looks like it will skip the flush/selftest
if it's being used as the console.
