I've set up my Dell Inspiron 8000 to have both the ps/2 touchpad and a
MS USB wheel mouse active simultaneously in both X and console text mode.
I am also able to activate gpm so that it sees both.  I'm running SuSE 7.1
under a reiserfs patched 2.2.19 kernel, and X 4.0.3.  I have not yet
succeeded in getting the wheel to scroll in X / fvwm2 though, and do have
problems getting the X clipboard paste to work in some X apps such as
StarOffice.
