Note sfb(4) framebuffer and lkkbd are initialized in consinit(9)
during early startup so kernel messages there were not logged,
but IIRC there was a message
>> lkkbd0: no keyboard
on sfb(4) screen just after the kernel was loaded.

So I'm afraid there is something wrong in lk201 keyboard driver
but it should work even with the "no keyboard" message.

Oh, TC USB on DEC3000 :-)

I have not tried multiple framebuffers on DEC3000, but
IIRC when I tried sfb(4) and tfb(4) on 3MIN (pmax)
I had to set "console" and "osconsole" variables
on the firmware properly. (or just remove sfbp temporaryly?)

Maybe just because it has not been tested or improved enough?
 http://cvsweb.netbsd.org/bsdweb.cgi/src/sys/dev/tc/sfbplus.c?f=u&only_with_tag=MAIN&logsort=date#rev1.8
Once it's confirmed working we should enable it in GENERIC,
though I'm afraid it requires more work (tweaks forrnewer gcc for
sfb(4), for example):
