I had submitted those changes to Benjamin, not sure what happened.
I've attached the proper mac_keyb.c file. Replace your broken one and
recrunch the kernel, and you should be set.

* Supported devices:

* - All standard Apple Extended protocol (handler ID 4)
* mice & trackballs
* - PowerBook Trackpad (default setup: enable tapping)
* - MicroSpeed mouse & trackball (needs testing)
* - CH Products Trackball Pro (needs testing)
* - Contour Design (Contour Mouse)
* - Hunter digital (NoHandsMouse)
* - Kensignton TurboMouse 5 (needs testing)
*
* To do:
*
* Improve Kensignton support, add MacX support as a dynamic
* option (not a compile-time option).

/*
The X server for MkLinux DR2.1 uses the following unused keycodes to
read the mouse:
0x7e This indicates that the next two keycodes should be interpreted
as mouse information. The first following byte's high bit
represents the state of the left button. The lower seven bits
represent the x-axis acceleration. The lower seven bits of the
second byte represent y-axis acceleration.
0x3f The x server interprets this keycode as a middle button
release.
0xbf The x server interprets this keycode as a middle button
depress.
0x40 The x server interprets this keycode as a right button
release.
0xc0 The x server interprets this keycode as a right button
depress.
NOTES: There should be a better way of handling mice in the X server.
The MOUSE_ESCAPE code (0x7e) should be followed by three bytes instead
of two. The three mouse buttons should then, in the X server, be read
as the high-bits of all three bytes. The x and y motions can still be
in the first two bytes. Maybe I'll do this...
