how 'supported' are 3ware Escalade controllers?

So - I took the plunge, and have sucessfully spun up a 7506-8 under
FreeBSD 5.2.1.

  # df /dev/twed0s1
  Filesystem   1K-blocks       Used     Avail Capacity  Mounted on
  /dev/twed0s1 1324492798 444478178 774055198    36%    /backups

Eight drives under RAID5, hurray.

I'm now exploring the misc management tools, with middling success,
but I'd love some feedback on what other people have successfully
gotten to fly:

- I've spun up 3dm, but, for the life of me, can't get it to send
  me email.  No errors, just silently doesn't do it. :/

- I've installed the smartmontools-5.22_1 package, but get this
  sort of diagnostic:

    # smartctl -a -d 3ware,0 /dev/twe0
    smartctl version 5.22 Copyright (C) 2002-3 Bruce Allen
    Home page is
    Smartctl open device: /dev/twe0 failed: Inappropriate ioctl for device
    # smartctl -a -d 3ware,0 /dev/da0
    smartctl version 5.22 Copyright (C) 2002-3 Bruce Allen
    Home page is
    smartmontools 5.22 does not currentlly support TWE devices (3ware Escalade)
    Smartctl: Device Read Identity Failed (not an ATA/ATAPI device)
    A mandatory SMART command failed: exiting. To continue, add one
    or more '-T permissive' options.

  This seems rather contrary to the docs in the package...

- This very thread I've replied to implies a 3dm2 out there, but I
  could find no reference on 3ware's site.  Was this something I imagined?

I suppose calling 3ware's support would be a next step for me...
