Jim and others, 

We did some work last summer with a Dy4-177 VMEbus board which came to
us with the VxWorks bootrom intact, and used a similar solution to
yours.  

The
binary-to-assembly convertor is a simple perl script which does almost
the same thing as vxWorks' binToAsm tool.

We are using a piggyback.c (different from the one in chrpboot)  to
produce the assembly.   It's probably no better or worse than the perl
script you've got.  

The initrd stuff would need similar treatment, but since I don't use
initrd, I haven't implemented it.

We DID find it useful to have initrd support, so our Makefiles can use
piggyback to make a tftp/vxworks loadable Linux kernel.   If this is
something you could use, please let me know.  

Cheers, 

Frank
