I see the problem but I don't think we want another module parameter
for it. I think if you put the following somewhere into init scripts
it shoudl work without any additional changes:

        echo -n "0" > /sys/bus/serio/devices/serioX/softrepeat

Of couurse one would jhave to locate proper serioX but that should be easy.

I also see the following in bugzilla: "... This causs a problem on
systems that have no real keyboard plugged in, since atkbd probes for
the keyboard, and won't take control of the port if it doesn't see
one." Usually it is OK for keyboard to be missing as long as BIOS
itself does not disable keyboard port - whenever there is new data
starts coming from the port serio core will try to find proper driver
for it. I wonder why this is not working on boxes in question.
