Let's see - I went through several machines and tried to find that node. Since they're all inside of Linux, I couldn't easily resolve /chosen/mmu, which btw didn't always exist either.

Apparently all our PPC32 machines are offline, so I can't easily check things there. If you like, I can boot up my iBook and see what I can find.

Hi Alex,
Thanks for the offer. Given that Igor has found the documentation for this in the platform bindings (and it matches what is seen in the source code), please don't worry about this for the moment. I shall post a patch for testing shortly.
ATB,
Mark.
