No, only current does, right now. I can provide anybody
who can't way for Ultra-SCSI support to be merged into
the -stable branch with a patch file, that brings the
2.2 driver to the -current level of features. If you 
want to receive that patch, send mail, and I'll either
send you a diff file or place it on some FTP site ...

If you can wait for one or two more weeks, then just 
watch the commit mail or CVSup logs for signs of the
patch having been committed :)
