Okay, thanks. Looks like I'll have to browse the OpenBoot source to find 
out the stack diagrams for these words to reimplement them in OpenBIOS.

There's also more huge chunks of Forth embedded in 
http://src.opensolaris.org/source/xref/systemz/sirius/usr/src/uts/sun4/os/startup.c 
to manage the TTEs aswell :(  Alas since these aren't part of the 
official OF specification, it's probably going to take some time to 
figure out which words/defers are missing and reimplement them.


ATB,

Mark.
