	My understanding is that regular vinum won't work on 5.x, you 
need geom-vinum for that.  Recent postings from Søren have lead me to 
believe that none of the ataraid stuff works with 5.x, either -- you 
can use them as plain ATA controllers, but the RAID stuff has not yet 
been worked out.

	That takes us back down to geom-vinum, geom-stripe, perhaps some 
SCSI RAID controllers which aren't affected by any of the ATA stuff, 
and maybe ccd.
