Made powerpc to get on PearPC to the version print when compiled with -O1:

  • create proper memory zones
  • switch to real mode on boot

TODO

  • kernel relocation during boot
  • autodetection of framebuffer settings (PCI?) - now includes hardcoded settings for PearPc.
  • Property mode set to 100644
