Yes -- on "insecure boot" boot/olpc.fth is read, but not on secure
boot. Notes at

If you want to see how the kernel params are setup in OFW, you should
look at OpenFirmware as of changeset 1145, in the file

You want to look for boot-file. Anyway, my quick review of the file is
that there doesn't seem to be a usable root parameter for that case.
If you look, *nothing* talks about mtd in relation to the boot-file

The initramfs code should check for the secure case, or at least the
"missing a root parameter" and set it.
