Is anything being done to un-break partition names?

That's your problem. In a DD setup, you don't have slices.

This is correct.

The bug is on your disk and as such in sysinstall. GEOM_PART_MBR
detects the MBR just fine. If you don't have GEOM_PART_BSD in
your kernel your will in fact get the MBR slices. The problem
for you is in the fact that you have a BSD disklabel in sector
2, which takes precedence. A disk partitioned as a BSD disklabel
nested in an MBR slice can *NEVER* have a BSD disklabel in the
2nd sector on the disk. The fact that there is a BSD disklabel
in sector 2 means that the disk is DD and that is what you get
for gpart.

FYI,
