There is no need to load this module with 2.4 kernels unless you use
an USB keyboard. But this solution doesn't work with 2.5 kernels because
all keyboard input goes through the input driver.

As a temporary solution I suggest the following patch:

--- ../linux-2.5.65.org/drivers/char/keyboard.c	Mon Mar 17 22:44:04 2003
+++ drivers/char/keyboard.c	Tue Mar 25 04:48:20 2003

                 .evbit = { BIT(EV_KEY) },
         },
 	

This way the keyboard driver will only accept keystrokes from a
standard AT keyboard.

Because of a small bug in the 2.5.65 input driver you need the 
following patch, too. (I already sent this to Vojtech.)

HTH,

Oliver
