Isn't that impossible because GRUB has its own GOT?  I mean: GRUB has
to lookup all symbols itself, etc.  If I am wrong, I have no idea how
to do it.

I hope to finish module loading so it at least works this weekend
using the method that can still cause overflows.  Can you have a look
at the code when I send it in and explain it using the GRUB code?

Thanks,
