No, newfs_msdos'ing and then mounting /dev/vn0, tho wrong, would have worked fine, and have previously. What I did later was I booted bochs, formatted the drive from inside bochs, installed DOS, etc. And then realized, stupidly, I couldn't mount the MS-DOS formatted drive because I wasn't using the right _slice_; so I mount dev/vn0s1c, and it works fine then. This is the same old problem as before... last time I saw it was with floppy disks, and I guess I thought it didn't affect other media like vn(4). BTW, if you didn't know, your mremap() for linux band-aid was merged into -CURRENT.
