You're seeing custom kernel patch to the "rootwait" option that prints
out the filesystems it sees every five seconds until it finds the one
specified by the "root=" kernel option.

It probably can't mount your USB device to get at the root file
system.  It could also be the "root=OLPCRoot" argument - could you try
with "root=/dev/sda1" or something?

It could also be that the initrd doesn't have the usb modules, or that
the initrd isn't being used.  Do you see OFW loading an initrd?

Thanks for testing this.  I wish I had more time to do it myself and
save you the trouble.
