Actually, I can now mount my old 4.x boot drive cleanly when I hook up this 
drive in a 6.2 machine.

However, I think I need to get the old boot drive to be able to boot, so I 
could then get to my other old drives, which are Vinum RAID-1.

I don't know if and how could I mount 4.x Vinum partitions under 6.2...
