Here you go!

I have a 2btn mouse on /dev/psaux and a keyboard pointer on
/dev/ttyS0(don't use the /dev/cua* devices they are not being used
anymore, especially for non-communication devices) and I use gpm to
control both on the console and act a a repeater(see the gpm man page)
for X.

/etc/gpm.conf:
device=/dev/psaux
responsiveness=
type=ps2
append="-M -m /dev/ttyS0 -t ms -r 2 -R"

                                   ^^^^
             I think this is not needed(the -M => -R) but it works.

Again see the gpm man page on the repeater section.

/etc/X11/XF86Config(Pointer Section)
Section "Pointer"
    Protocol "MouseSystems"
    Device      "/dev/gpmdata"
    Emulate3Buttons
    Emulate3Timeout    50
EndSection

Note that you can modify the responsiveness of the individual
mice/pointers/pads with gpm but that only works for the console
pointer.  When using the /dev/gpmdata device gpm does not modify the
inputs. So if one is more responsive than the other you will have to 
live with it or adjust xset to a happy medium for the two in X.

Enjoy,
Brian
