It seems that the right thing to do here is to invent a new "wsjoy"
device for wscons, which has all the features we need. wsjoy could be
self-describing (an ioctl for "tell me how many buttons you have, and
how many control axis you have", or something).
Then the ISA/PCI joystick and USB joystick and Dreamcast game controller
drivers would be back-ends for wsjoy, much like pms, mms, etc. are back-ends
