Speaking of this, I just tried to compile an official (Linus' git tree)
kernel for my old PMac G4 and I get a lot of section mismatch warnings at
the end of the compilation:
LD vmlinux
SYSMAP System.map
SYSMAP .tmp_System.map
MODPOST vmlinux

I find these 50 or so warnings so scary that I've not yet tried
to boot the kernel. Note that this is a non-modular kernel.
