hmmm, isn't already done in 8.X ? 
from what's cooking for FreeBSD 8.0
bsdlabel gets extended to 26 partitions

Status: Committed to -CURRENT
Will appear in 8.0: sure

Web: commit message

bsdlabel is (finally!) extended to support more than 8 partitions. The
new limit of 26 partitions comes from the number of lower-case letters.

To make use of this change, GEOM_PART needs to be used instead of
GEOM_BSD (this is default in 8.0 but will not work with older kernels).
