SubjectLinux 2.2.5 crash via /dev/port

Here a method how to `crash' Linux. Since I don't know exactly to
which area this belongs, I'm sending it to this list.

First, I've patched apmd to include the line

system("/sbin/kbdrate -s -r 30")

which will be executed after resume -- BTW, this has worked with the
2.0.x kernels, but now I get the message

ioctl(KDKBDREP): Inappropriate ioctl for device

Why? Can somebody tell me how I must do this correctly? My Laptop
BIOS always resets the keyboard rate, so I want apmd to set it to the
above value after each resume.

OK, I've closed my Laptop, opened it again, see this message and then
do a

cat /dev/port

and Linux crashes, i.e., it doesn't respond to any key combinations.
