[OpenBIOS] resend: [1/5] Open Firmware on LinuxBIOS on M57SLI

[Torsten Duwe]

As on http://www.openbios.org/Open_Firmware, change the config to get a 
suitable ELF header. qemu-loaded is also necessary on real hardware for 
current openfirmware versions. pc-linux will get you the capability to load 
ELF kernels from EXT2 file systems :-)
virtual-mode somehow doesn't work for me.
