Might be interesting but not much.

If you plug an external USB keyboard and do:

	echo -n "reconnect" > /sys/bus/serio/devices/serio0/drvctl

or

	echo -n "rescan" > /sys/bus/serio/devices/serio0/drvctl

after booting does it revive the keyboard? Also, what does
/proc/interrupts look like?

Thanks.
