I was kind of hoping that someone else would lend a hand :-)

And shared libraries? I have not gotten that to work yet :-)
I still have problems with COPY relocations.
I've also kludged the interpreter to load at 0, because otherwise
it tries to reference relocatable symbols before it gets a chance
to relocate them.

What are the errors?

Hmm, I thought I committed that one.

Again what are the errors?

	#ifdef __ELF__

I was planning to work on that after I got the shared library stuff
working. And after I got the elf kernel, I would go for the elf lkms.
I have not looked at the kernel/booter. It should be pretty easy to
fix though.
