>Description:
Currently, the track pad for a 14.1" macppc is not recognized by the pbms 
driver. This is due to the product ID not being present in the driver.

This patch introduces the track pad driver support. I have also experimented a 
bit with the x sensors and y sensors value to make it have a fairly good 
control of the track pad. ( it isn't perfect though)


>How-To-Repeat:
Install the MacPPC port on a 14.1" ibook G4 and start X.org and notice the lack 
of trackpad support
>Fix:
Apply the following patch to the netbsd-4 branch:
Looking at -current code, it appears that a similar change needs to be made to 
it as well.
