The kernel supports forcing a root filesystem type, using the
"rootfstype" kernel parameter, so something like "rootfstype=yaffs" will
ensure that you get the one you're after.

Normally this is a good idea anyway, as it avoids the error messages
that the other filesystems emit when they fail to mount your mtd device.
