That interface isn't complete: the GNU Mach kernel uses linux drivers
internally, and the scsi_ioctl() function is available there (thus with
the linuxish interface), but its features have not been propagated to
the device_get/set_status() user interface yet. It should be quite
easy to add it, however, see the device_get/set_status() functions in
gnumach/linux/dev/glue/block.c
