What about before X starts? Can you please boot into console, kill
hal and udev to make sure they don't mess up with the keymap and, after
doing

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

which should completely reinitialize keyboard and compare
/proc/bus/input/devices again? If it is still the same then there must
be a silly bug in X's evdev... But regardless, X policy of comparing
keybit is stupid - they don't kill the device if I change keymap while
in X, why do they do that on resume? Or when I change the limits on
absolute axis... Oh well.
