Thanks for you work it's a huge progress.

I have just tried here, with a Debian Lenny kernel, and the kernel
doesn't print anything. Would it be possible to share your kernel config?

It seems the "NULL ihandle" message is printed by OpenBios, so I guess
the kernel simply exits because it does not find what it needs in the
device tree.
