  Nothing should have changed as far as the IOCTL calls from mt, since both
the old Amiga st driver and the new scsi one used the same definitions
(in sys/mtio.h).  However, the interpretation of the minor number has changed.

  The Amiga driver expects the tape device to be defined as follows:
	/dev/rst0	minor number = 0
	/dev/nrst0	minor number = 4

  The new st driver expects the following:
	/dev/rst0	minor number = 0
	/dev/nrst0	minor number = 1
If the existing /dev/nrst0 (minor number = 4) is used, the 4 is one of the
density bits, so it will still rewind the tape device.
