Yes -- on "insecure boot" boot/olpc.fth is read, but not on secure
boot. Notes at http://wiki.laptop.org/go/Boot_Process

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
cpu/x86/pc/olpc/fw.bth

http://tracker.coreboot.org/trac/openfirmware/changeset/1145

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
parameter.

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

cheers,
