  There were some changes recently in the mouse module in xfree, some PS/2
mice were broken for a while but that has been fixed before 3.9.18, I don't
a usb mouse at my mac so i can't help there but IMPS/2 works fine in my x86
machine.

  I am not sure but i think that 3.9.17 was using the same code as well,
probably one of the changes in mouse.c broke something. Is it IMPS/2 the
right protocol for the ppc usb mice btw ? If our usb code uses 3 bytes
then its not using the IntelliMouse protocol (which is 4 bytes as i can
see in the code).

  Can you try with the other PS/2 protocols and if you still can't get
the mouse working try with older mouse code from 3.9.17 that will help
tracking down the problem.
