It apparently uses a modified version of the Sun mouse protocol.
Attached are the sunmouse driver patch and the gpm patch. The gpm patch
could be worked around trivially by having the kernel driver emulate a
regular Sun mouse, but I'm hoping for some feedback on this from the Sparc
kernel developers instead of just committing to the CVS tree.
In the meantime, enjoy.
