I'm always happy when I can fix bugs.  Though not always happy to
discover that the d*ckhead who created them was me.

You can use mtd0 instead of /dev/mtd0, similar to jffs2.  Any /dev/foo
gets interpreted by some common code in the kernel.  As it's not a
block device, mount fails.  mtd0 doesn't start with /dev/, so it must
be special somehow and gets passed to the filesystem.  Jffs2 and logfs
are can then do something with this string.

And yes, this sounds really stupid.  Having /dev/mtd0 do the right
thing would certainly be less confusing than the current state.
