Yep. There are two problems at the moment, which I should get off my
butt and fix. :-)
The first is that the current machines use a different structure for
nvram, based on the CHRP spec, which means that just using a fixed
offset in nvram doesn't work. In fact it seems like macos adds a OF
property with a really strange encoding to store arbitrary bits of
information for the device drivers for arbitrary devices.
The second is that macos is now using mode numbers > 20. I haven't
worked out the correspondence yet.
Paul.
