I can confirm that 'classic' vinum will panic if loaded before other non-
vinum partitions are mounted. (on a 5.3-STABLE SMP box).

This is not too encouraging either:

> man gvinum
No manual entry for gvinum

:(

Right now I am in the middle of replacing a dead disk in my 'classic' 
vinum raid5 volume. Thinking that now might be a good time to check
out gvinum, I tried this command (despite the above message):

# gvinum load
unknown command 'load'
#

...but geom_vinum loaded anyways! But it got it wrong :(
The following, which appeared in /var/log/all.log, should
all be the same subdisk name. It looks like gvinum found
some old volume info.. I have used both volume names, but
now should only be one (holden):

Nov  8 09:13:08 <kern.crit> hummer kernel: GEOM_VINUM: subdisk hewey.p0.s2 is up
Nov  8 09:13:08 <kern.crit> hummer kernel: GEOM_VINUM: subdisk hewey.p0.s1 is up

Nov  8 09:13:09 <kern.crit> hummer kernel: GEOM_VINUM: subdisk holden.p0.s0 is up

(ps. why is this a 'kern.critical' error?)

and now it looks like I can't get rid of gvinum to go back and try 
'classic' vinum:

# kldstat
Id Refs Address    Size     Name
  1    4 0xc0400000 2bd7e0   kernel
  2    1 0xc1af1000 2000     green_saver.ko
  3    1 0xc1dfa000 10000    geom_vinum.ko
# kldunload geom_vinum
kldunload: can't unload file: Operation not supported
# gvinum unload
unknown command 'unload'
#

Oh well.. reboot, here we come..
