Yes, we need more patches:

- for qemu, an nvram cleanup I already sent some month ago, and a little PCI 
cleanup patch.
- for openbios, at leat one patch to remap ROM in RAM.

I'm working hard to make them available, but currently, openbios is able to 
load Yaboot and Yaboot is able to load linux, but linux crashes when it is 
building its flattened device tree.
