I have never seen this MAKEDEV script (where does it come from?), so I
can't say what patch it talks about. But here's a patch from Dean
Troyer, which is supposed to fix the driver on some laptops. (PS/2
mice are not bus mice, by the way, so the MAKEDEV script may be
referring to some other type of mouse.)

As of XFree86 version 1.2 this isn't needed anymore, v1.2 already
knows the PS/2 mouse protocol, so there's no need to emulate a
Microsoft mouse.
Other things to check if the PS/2 mouse isn't working:
- see if you can produce any output with the command 'od -c
/dev/psaux' (Or whatever the PS/2 mouse is called on your machine... I
guess the PS/2 mouse device name fell for the NIH disease... Anyway,
it should have major number 10 and minor number 1.) Moving the mouse
should print a stream of bytes on the screen.
- Make sure you have the right entry in Xconfig: for XFree86 1.2 it
should be PS/2 "/dev/psaux" (Or whatever the PS/2 mouse is called...
(grr..)) For XFree86 1.1 and older you *do* need the protocol
converter. In this case the mouse type should be Microsoft.
