Small buttons of the keypad mouse work as the wheel button of PS/2
Intellimouse. The mouse sends 4 instead of 3 bytes of info to the aux port.
The last byte contains 1 (0x01) or -1 (0xFF) if the left or right button is
pressed. The most annoying feature is that these buttons have autorepeat.
They send events every 150ms (400ms between first and second event) while
they are pressed.

I modified the kernel I am running to map these two buttons to button 2 and
created a program (stealing some code from pipefile.c) to replace button 2
presses that are within 150ms with one press and one release. Using the
small buttons as button 2 is still annoying but is better than nothing.

If my changes are of interest for anyone, I'll clean them up and post them.
