This is GREAT news! We have a hint to start with.

i8042.c linux kernel source code defines more module parameters. The module 
parameter "direct" disables the scan code translation, but the module parameter 
"dumbkbd" completely disables the write capability of the kernel module to the 
i8042 controller and this actually makes the problem totally disappear!
The only side effect I noticed by now is that the keyboard leds don't react 
anymore to the lock status (ie: the Caps Lock led won't turn on).

I think there is some configuration/setting keyboard controller doesn't
like and makes it misbehaving, thus disabling completely the write
capability solves the problem.
