bin/122235: freebsd-7.0 moused problems with ALPS GlidePoint

[J.R. Oldroyd]

Running moused -d gives the following:

moused: proto params: f8 80 00 00 8 00 ff
moused: port: /dev/psm0  interface: ps/2  type: sysmouse  model: GlidePoint

Using the touchpad to move the mouse around in circles within an
xterm window gives me many movements similar to the following:

moused: received char 0x87
moused: received char 0x0

After a few minutes, while still moving the mouse in circles,
suddenly I get this:

This continues for several entries and then the trace returns to
normal.  The above shows moused "receives" clicks on several
buttons simultaneously, including non-existent buttons.

At the time of these false button presses, text where the cursor
was is selected and then pasted back into the window.

Observe that before these false packets, several bytes are received
that appear to be ignored.  Possibly these are the end of a previous
packet of which the first bytes are being lost?
