Simple: start GPM with the repeater flag (-R <repeater type>). This will
cause GPM to open the /dev/<mouse_dev> device for reading, interpret the
commands as it normally would, but also repeat the commands verbatim to
/dev/gpmdata.

The reason why X didn't work while GPM was running prior to starting X was
because GPM opened the /dev/<mouse_dev> device first. Under Linux, only the
first program that opens a device for reading and/or writing gets the
privelege of reading and/or writing to it.

Have a look at the gpm(8) manpage for more information.
