too difficult to do, but in essence, local compile of FreeBSD 6.1-RC on Sparc64 (An Ultra60) done 3 May 2006 with latest cvsup.
I have a usb keyboard and a Sun keyboard. The Sun keyboard works, but the USB one doesn't. (On the version of FreeBSD 5.4 installed on a different partition, the USB keyboard does work.)

I tried to deselect the sun keyboard with
kbdcontrol -k /dev/kbd0
and the error message says
sunkbd0, type: generic (0)
WARNING PID 549 (kbdcontrol) ioctl sign-extension ioctl ffffffff80244b45
Unable to (un)mux the keyboard - operation not supported by device

I tried using kldload to load the kbdmux, and this made no difference.

kbdcontrol -K /dev/kbd0
produces a kernel panic!

kbdcontrol -A
kbdcontrol -a
also do not work correctly AFAICT.

Use kbdcontrol on an Ultra60 with a Sun type 5 keyboard.
Not known.
