Gpm running with PC-like parameters

[Ismael Valladolid Torres <ivalladt@punkass.com>]

For me, it's quite surprising that gpm works perfectly with device as
/dev/psaux and type as autops2. This is a B&W G3 where mice should be
at /dev/input/mice and the type should be... Anything else?

Any feedback welcome!

Cordially, Ismael
