1)	The NetBSD driver is an easy port... no more difficult than
	installing another disk, which you will need to do to make
	it work anyway.  Native support, at least as far as I'm
	concerned, hinges on integration of devfs as the default
	device access mechanism.

2)	There is a Compaq SCSI comtroller that has transparent RAID.
	There is a driver for FreeBSD, although it hasn't been
	integrated.  Look at the -hackers list archive, subject
	"Re: RAID" for details on the Compaq controller.  Software
	RAID is pretty much unusable because of [lack of] speed,
	although there was talk at one time of altering the AIC-7770
	based controller's sequencer code (since it is home brew
	anyway) to support RAID at that level, which would make it
	more realistic.
