That's very, very strange, and shouldn't be possible.  What are
you doing differently to me:

	# uname -v
	FreeBSD 6.1-PRERELEASE #19: Sun Feb  5 04:58:29 GMT 2006      
root at shrike.private.submonkey.net:/usr/obj/usr/src/sys/SHRIKE
	# dd if=/dev/zero of=/a/md bs=1000 count=6144000
	# mdconfig -a -f /a/md
	md2
	# geli init /dev/md2
	# geli attach /dev/md2
	# newfs -U /dev/md2.eli
	# mount /dev/md2.eli /mnt
	# ls -ld /mnt
	drwxr-xr-x  3 root  wheel  512 Feb 11 15:15 /mnt
	# chown ceri:users /mnt
	# ls -ld /mnt
	drwxr-xr-x  3 ceri  users  512 Feb 11 15:15 /mnt
	# umount /mnt
	# mount /dev/md2.eli /mnt
	# ls -ld /mnt
	drwxr-xr-x  3 ceri  users  512 Feb 11 15:15 /mnt

That must be wonderful!  I don't understand it at all.
