External symbols that just point to the kernal are located in kernal.s. If
additional code for a function is needed, it will go into a file with the name
of the function and a 'k' prepended, so the new plot function can be found in
kplot.s.

Yes. "VC20 intern" rulez:-)

Yes, that would be a very good idea. Unfortunately, in the current state this
would mean to add a new target to the linker, and I'm trying to avoid such a
proliferation. I've already added a new feature to the linker that allows to
add a default value for the start address, but this is only one additional
step needed. So it will happen, but not now.
