This is a problem with sysinstall. It looks like DD is broken.
MBR partitions are always created. GEOM_PART correctly uses the
BSD disklabel that's in the 2nd sector, but GEOM_MBR claims the
MBR being unaware that the disk is DD.

In other words: GEOM_MBR is broken in that it claims the MBR
for DD configurations, when GEOM_BSD should actually have
claimed the BSD disklabel. libdisk is broken in that it should
not create MBR slices for DD configurations to begin with...
