How do you load vxWorks? I have worked on several vxWorks projects,
and all of the systems had the vxWorks TFTP loader in the rom. Use
the same thing (whatever that is) to load the Linux/PPC image.
The zImage is linked such that you can just treat it as a bag o' bits
to dump into memory. Even with non-standard boot loaders, all you
need to do is write a simple program to strip the 64K ELF header, place
your own header on the top, make sure it gets loaded above 0x180000
and jump to the start of the image.
