Beige G3 device tree

[Programmingkid]

I finally obtained a Beige G3 for comparing with our emulated model. The model is very wrong. No wonder Mac OS X won't boot. What it expects a Beige G3 to look like is not being supplied. It is going to take a lot of changes to QEMU and OpenBIOS to fix things. My current guess why Mac OS X stops where it does is because of the missing ide@20000 node under the mac-io@10 node.

Here is a real Beige G3's device tree:
