The Be bootloader cannot run our kernel or vice versa.
The app used on Mac to bootstrap might, like BootX, but I don't think 
they maintain the OF environment for us to use...

BFD (the library used by binutils) now supports PEF, no need for a 
tool.
And we don't need to touch the kernel, just the bootloader.
