It's implemented in xf86-input-joystick's backend_bsd.c file and it's pretty generic (here of course trimmed for joystick use). Of course the interface is BSD-only (don't know about Solaris) but if the interfaces are somewhat compatible one could of course thing about wrapping it in the server, like the joystick driver does for itself.
