Subject2.6.9+ keyboard LED problem

The input changes in 2.6.9 made keyboard LED setting unreliable. 2.6.8
is OK, 2.6.9, 2.6.10 and todays BK are buggy.

The problem is that setting the LEDs now interferes with keyboard and
ps/2 mouse input and makes the kernel lose key press and key release

Short demonstation:
while :; do xset led 3; xset -led 3; sleep 0.01; done

This script works from X but the same effect can be seen on the console
using setleds. The problem was found with ledcontrol package but is
easyly reproduced with the script above.

Key press and release events are lost, mouse movement is lost or
movement is converted into clicks or mouse loses sync (by dmesg info).
There are also messages like
atkbd.c: Unknown key released (translated set 2, code 0xe0 on isa0060/serio0).
atkbd.c: Use 'setkeycodes e060 <keycode>' to make it known.
in dmesg.

Don't try the script without the sleep command unless you have a network
connection to log in and kill the script ;)
