No, this isn't what Frank mentioned about running an old fsck binary and 
losing the superblock. Well, it kinda is.

This partition also mounts without superblock.

It is also using (I imagine), FFS_EI as I originally made this partition on a
Mac OS X machine.

My sources are the same as my kernel (note I'm +1000 GMT)
