I've been doing it with a slightly different operation but yes it seems 
to be a
better way than jumping in after linking and patching up the kernel 
image.

Even if one is concerned about toolchain portability something like this

for every other (reasonable) toolchain I can think of.

I've hacked up an example of how to do all this and tested it 
extensively.
Let me know if you'd like copy of it.

Cheers,
