No, I've only used a setup that had both PS/2 and USB keyboards.
Just reading the kbdcontrol man page, the other thing you could try
is the -K option to detach the keyboard. e.g:

device "Keyboard"
 	devname "ukbd0"
 	attach "kbdcontrol -k /dev/kbd0 < /dev/ttyv0"
 	detach "kbdcontrol -K < /dev/ttyv0"

(or experiment with kbdcontrol -K from ssh)

BTW, what are the last few lines of `dmesg' after the keyboard stops
working?
