The actual code to do the work of loading modules is in
sys/arch/i386/stand/boot/exec.c
So is platform specific.

All I actually did was copy the module and load commands from the other
bootloaders to actually support modules.

There was the tweak to tftp, as loading a module does a stat on the file
so it can allocate the necessary memory, then load the file into that
memory.

There wasn't really much that wasn't just reusing what's there already
and tweaking it to work.

Thanks,
