I do not have an unknown type for my root partition, but I do have the 
rootfs partition:
$ mount | grep '/ '
/dev/md0 on / type reiserfs (rw)
$ cat /proc/mounts | grep '/ '
rootfs / rootfs rw 0 0
/dev/root.old / cramfs ro 0 0
/dev2/root2 / reiserfs rw 0 0

I am running sid, 2.6.6 deb image.  I believe the cramfs is the initial ram 
disk image.  Perhaps that may be why my root partition is a known type.
