Are you using the standard way of doing this, config tool and makefiles?
or did you just extract the source, because ...

just about everything. You need to see how the Makefiles package up the
kernel so that linuxbios can put it into memory.

I think maybe yes. I think you need to look at how kernels get built and
integrated into a flash image. If you want to send me your code files I
can plug them into the tree and you can try to work with that.
