Obviously, the other cards are missing. I can contribute RayDAT, if need
be (since I don't use the config ioctl at all, at least I don't need
it).
Fredrik: Do you still work on your hdspconf patch for hdspm? If so,
you'd probably be affected. Add "case MADIface:" below "case MADI:" to
see if it works.

	statusregister =
		hdspm_read(hdspm, HDSPM_statusRegister);

	status.card_specific.madi.madi_input =

		(statusregister & HDSPM_AB_int) ? 1 : 0;

MADI input (BNC/Optical) is a config option.
...
	status.card_specific.madi.channel_format =

		(statusregister & HDSPM_TX_64ch) ? 1 : 0;

		(statusregister & HDSPM_RX_64ch) ? 1 : 0;

This was simply wrong in the current driver: the status struct should
not tell if we're sending 64ch format, it should inform the user if
we're receiving 64ch on the wire.
