[OpenBIOS] [PATCH] Fix Linux/x86 load without virtual-mode

[Torsten Duwe]

Release early, release often.

Openfirmware seems to insist on virtual-mode when loading a Linux/x86 kernel 
as plain ELF binary (vmlinu_x_). Here's my proposed fix to load and launch it 
when virtual-mode is not defined. Qemu+gdb confirms the loaded kernel makes 
it to the halt after panic, at least. I'll have to see yet what's wrong with 
earlyprintk.
