Before spending time on this, be warned that I tried this for mxge
last year, and I gave up because it was such a headache.  The final
straw was that building the firmware into a .fwo file via a files file
rule doesn't work on platforms like ia64 due some toolchain problems.
Specifically, there was no way to get the constant-gp flag set on an
ld -b binary image, which caused the final kernel link command to

Rather than use the .fwo method, I committed some .c shims (see
dev/mxge/mxge_eth_z8e.c) which just #include my firmware header files.
This avoids the linking problems, and turns out to be much, much
easier to work with than the fw_stub files file method.
