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...
