Believe it or not nothing has changed in this area over the last week.

It's possible that the order of the 'file-system' directives in your kernel
config does not match GENERIC, and that msdosfs_mountroot() is erroneously
identifiying your root as a FAT file system before ffs_mountroot() gets to
look at it.

Was there a FAT FS on that partition before? Could you put the first sector
of the disklabel partition up for download?
