This should be supported by the aac(4) driver in NetBSD-current.

There's a bunch of hardware RAID cards that NetBSD supports in
NetBSD-current, and most of these are probably in NetBSD-1.6 as well:
	* 3Ware 6x00 parallel ATA
	* 3Ware 750x parallel ATA (current card)
	* 3Ware 850x serial ATA  (current card - fast too!)
	* Adaptec 2400A parallel ATA
	* Adaptec 2100S/3200S/34x0S SCSI
	* ICP (was Intel for a while, now Adaptec) "Vortex" cards,
	  include SRCS31U SCSI and SRCS14L serial ATA
	* LSI (formerly AMI) MegaRAID

Not sure about:
	* Adaptec 2410A serial ATA (haven't seen this 

I have a bunch of these for testing, and at the moment I really like
the 3Ware 8506-8, although an 8506-4 would suffice for my production needs.

I personally find good hardware RAID cards easier to setup and use
compared to software RAID solutions.  Their performance is often
better as well.  YMMV.
