*If* you want to manually do this (since Volume Management does it for
you (;0)), you can open the floppy using the O_NDELAY flag, then use
the FDGETCHANGE ioctl to check for floppy presence.  NOTE, though,
that this steps the floppy motor on most SPARC drives (i.e. all but
the voyager, which has auto-detect floppy hardware), so programmer
beware.
