I'm partway through porting Vojtech's Linux joystick code to FreeBSD, as =

series of loadable modules. There is the main module (which is mostly =
converted, although some of the Linuxisms are a bit hard to come up with =

equivalent to, even with the Linux device drivers book) and a seperate mo=
dule =
for each of the different hardware devices. You'll kldload the main modul=

first, then the device specific module, which'll call a joystick registra=

routine to make itself known. You've just spurred me into action and I ho=

get the main module finished this weekend.
The recent chatter about allowing kldload to give modules arguments is ve=
