Just to double-check: is the mouse definitely connected to a usb port 
on the pc, or does it go via a usb-to-ps2 adapter, into a ps2 port on 
the pc?

I've got what sounds like exactly the same mouse here, on the system 
used to build lfs-6.5 plus gpm (& wget, links, and lynx) (per LFS-6.5 
section '9.3. Rebooting the System'): the mouse has that same 
"IntelliMouse(R) Optical USB and PS/2 Compatible" printed on its 
underside; although, of course, it could be pertinently different 
hardware 'under the bonnet' to what you've got, given how things can 
differ across countries or even across versions within a country.

The mouse here has a USB connector at the end of its cable, and that 
connector plugs into the usb port of a little usb-to-ps2 connector, 
which in turn has its (i.e. the adatper's) ps2 port connecting into a 
ps2 port on the back of the pc.

Worked first-time here with config file:
----
MDEVICE="/dev/mouse"
PROTOCOL="imps2"
GPMOPTS=""
----
And /dev/mouse is a symlink to /dev/input/mice ; and the latter looks 
ok re perms, ownerships, nodes, &c.

Just thought it worth a double-check on that connector.
