What your switch statement does can easily be done using
BPartition::IsPartitionable(), which (unless I'm mistaken -- I
remember, we discussed that) returns whether the partition's disk
system is a partitioning system.

Mmh, maybe I misunderstand you, but a BDiskSystem is not necessary to
get a BPartition. The only we to get a BPartition is via
BDiskDeviceRoster. I think, GetDiskSystem() is not only useful, but
even necessary. Since how, otherwise, would one get the responsible
disk system otherwise? The partition's type can't be translated to a
disk system name, I believe.
