I got the same result with FreeBSD 4.11, one drive working but not the
other. After redoing the disklabel, I got the other drive to load as
well.

Clearly vinum is broken when compiled with gcc3. FreeBSD avoided this
problem because when they switched to gcc3, they also had to rework
vinum to interface through geom.
