If they're just basic gameport joysticks, you might be able to get away with just loading the gameport and joystick modules and possibly the adi modules (for the Logitech). On my setup, I have to load ehci-hcd, usb-ohci and hid instead of gameport because my three Logitech game controllers are connected via USB but as yours are only Gameport sticks, you shouldn't have to worry about all that. The easiest way to check if their working after you've loaded all the modules is to cat /dev/js0 (if you're using devfs, this probably won't appear until all the modules are loaded properly which is another clue) and then move the stick around a bit. If you see output then chances are it's working.
