There is no umsdos driver for FreeBSD. Linux does this by establishing an attributes file called "--LINUX-.---" in each directory of a subtree hierarchy to combat POSIX non-compliance of the FAT FS. This should probably be called "-UMSDOS-.---" to be OS independent, IMO. The file is used to store attributes (uid/gid/ctime/modes) for the files in the directory. Obviously, this file is not updated or respected by DOS when accessing the FS. This requires a second stage boot that knows about the FAT/UMSDOS FS (or, more typically, Linux uses a boot floppy that mounts / from the hard drive from a "/linux" directory under the FAT root that has UMSDOS permissions on the underlying hierarchy. One alternative for FreeBSD is to make a boot floppy and then use vnconfig to configure a DOS file as a file system and mount it. This is a bit of work. Is there some technical reason that you need to use a 8-10 times slower FS to store your files?
