It's been available to selected parties that have been participating in 
its development.  Simon was at the 'con and indicated that it's close 
to being ready for 3.x systems now.

You can't have been looking very hard; all of the major vendors have U2W/
LVD controllers and have for many months.  In addition you can use most
of Mylex and AMI's U2W/LVD PCI:SCSI controllers with -current, and I've
just backported the Mylex driver to -stable as well.
