This rumor might be substantiated by a quick look at the Atari and Amiga
floppy drivers. My prediction: the ioctl in question isn't implemented, or
the ioctl data size mismatches. 

Both Amiga and Atari implement FDGETPRM. Atari also implements FDSETPRM
and FDDEFPRM (and those used to work at the time they were written).
