This mess is because when reading the gvinum configuration on boot-time, none of
the objects is actually bound together and registered within another when the
drive_taste is run (The parser just creates the object. It does not bind
anything together). The states is also not updated. I've already done some work
on this, but I discovered more issues that need to be fixed.  I'll try have a
patch ready by tomorrow night.

I also have several other fixes in the lulf_gvinum_bugs branch in p4 Lukas.
