I see that the log(LOG_DEBUG, ...) never get logged (nor in dmesg).

I used:
  options SC_HISTORY_SIZE=2000
and now I can scroll back to also see (manually typed in):

kbdc: new command byte:0054 (set_controller...)
kbdc: TEST_AUX_PORT status:ffffffff
kbdc: DIAGNOSE status:0055
kbdc: new command byte:0065 (set_controller...)
