I have the same patch locally, but I don't think its the right way(c) to do
it. IMHO, we should implement DIOCGDISKINFO ioctl(), and get rid of
WEDGEINFO and PARTINFO entirely here.

I am currently looking for the correct way of getting prop_dictionary
entries ("sectors-per-unit" out of "geometry" proplist) out of the struct
plistref, or simply find another solution around VOP_IOCTL().

Cheers,
