Hum, that question sounds familiar -- see below. In your case, you're obviously
on the new input layer. What happens when you do a 

cd /dev
ln -sf input/mouse2 mouse

(if this wrecks something, do a

ln -sf input/mice mouse

to restore your input)?

:If you're still using the old input layer, you might use /dev/gpmdata as
:mouse device (or you probably do already, if both devices are working).
:Then you could restart gpm w/ or w/o multiple input devices. Might be a bit
:cumbersome, but it's possible while X is still running.
:Maybe with the new input layer it's simply possible to replace the link
:/dev/mouse -> input/mice by a link to a single mouse device (input/mouseNN,
:iirc), but I've never tried that. This probably won't work without restarting
:the X session. Ben?
