IIRC, the unresolved issue was exactly where to put them. Presently,
"disklabel -r" writes to the upper half of block 0, which interferes
with the LaCie driver. It seems to only put private settings there for
use of the partitioning utility--the driver works fine as long as you
don't try to launch the utility, which then demands that you
re-install the driver.

I'd consider putting it inside a proper Apple Partititon Map
partition. That way gives you enough rope to hang yourself. :-) 
In any case, the general consensus was that the i386 way, of looking
for it in several different places, kind of blows.

Where did your patches place the disklabel?
