Every now existing OS Kernel would run on that BIOS! Normal 32-bit OSs
don't use the 16-bit BIOSs now available. If openBIOS loads the kernel
correctly, there are no problems with kernels like Mach, wich allready
assume they are loaded by the bootloader in pmode etc... if openBIOs
supports the multiboot standard, there will be no problem.

Its only the boot loader that wouldn't run with the openBIOS, but if
openBIOs includes the bootloader itself, so no bootloader will have to be
included on disk...
