The powermac emulation isn't ready yet but may work soon (I hope !)
I'd like to see some hw manuals, if you can send some to me or give me
URLs if some are available from the net.

I implemented quite the whole OF and RTAS interfaces. I didn't implement
Forth, as I can do without to launch Linux and OSX. It seems that I may
be able to launch a lot of OSes this way, but I may need to merge a real
Forth interpreter for some others.

Now, I can boot Linux without disks and start booting OSX (ie launch and
initialize the kernel). There are problems due to:
- bugs in the BIOS OF tree.
- hw emulation buggy or missing or not declared/used.
Most of the hw stuffs have been writen but not tested in "real"
conditions, so the work to do in qemu is now to get all hw components
work together and get debugged.
