turbo mouse driver fix...

[Mark Abene <phiber@radicalmedia.com>]

Hey!  Please test the following patch to mac_keyb.c which fixes the TurboMouse
support you added based on my "mousehack" program.  I tested my changes on a
2.2.7 kernel.  The problem is that once you determine we are working with a
TurboMouse 5 (thanks for adding the reg 1 ID detection, btw!), we need to write
to id 3, which is how you control the TurboMouse 5's modes, not to id 15.

That should work fine.  If it does for everyone else, it should be committed!
