NetBSD X does not support multi-headed - Ultrix X does.

This sounds like a TURBOchannel prestoserve card.  The SIMM card appears
in the output of "cnfg 3".  I'll send some output next time I have a
machine with one down.  It's something like:

	mem(13):  aXXXXXXX:aXXXXXXX  (  2 MB) NV-RAM

This is a restriction of the current MD pmax SCSI tape driver, and applies
to all systems.  It isn't hard to support other SCSI ID's, and when we
switch to MI SCSI this will be fixed.

The DEFTA FDDI card _is_ supported:

	fta0 at tc0 slot 2 offset 0x0: DEC DEFTA TC FDDI SAS Controller
	fta0: FDDI address 08:00:2b:a6:13:ea, FW= 1.1, HW=2, SMT V7.2
	fta0: FDDI Port = S (PMD = ANSI Single-Mode Type 1)

This is from a 1.4-release branch kernel.
