I think this is what I'm using, re-labeled as DELL CERC (4 ATA channels):

  amr0: <LSILogic MegaRAID> mem 0xfeb00000-0xfeb0ffff irq 5 at device 7.0 on pci0
  amr0: <LSILogic CERC ATA100/4ch> Firmware 6.61, BIOS 1.01, 16MB RAM

It looks like and matches the docs at:

  http://www.lsilogic.com/products/stor_prod/raid/i4.html

Seems to be working fine under FreeBSD-5.0-RELEASE, 5.0-CURRENT and
5.1-CURRENT.  Looks like:

  amrd0: <LSILogic MegaRAID logical drive> on amr0
  amrd0: 9999MB (20477952 sectors) RAID 5 (optimal)
  amrd1: <LSILogic MegaRAID logical drive> on amr0
  amrd1: 111093MB (227518464 sectors) RAID 5 (optimal)
  amrd2: <LSILogic MegaRAID logical drive> on amr0
  amrd2: 111093MB (227518464 sectors) RAID 5 (optimal)
  amrd3: <LSILogic MegaRAID logical drive> on amr0
  amrd3: 111099MB (227530752 sectors) RAID 5 (optimal)

Searching for RAID stuff, Michael Smith

pointed me to Eric Dean Moore <emoore@lsil.com> who's working on this
and appears to have multi-user-level support for monitoring and
controlling at:

but I haven't had a chance to check it out yet.
