Thanks for the pointers. I had forgotten there was supposed to be
some GUI memory layout tool that auto-generated stuff.

That looks like what I needed. In the end, I just put some absolute
symbol assignments in my .ldi file to get the vector table located in
the right spot, while the "vectors" section contains only the
program's entry point. It's ugly, but it works. One day I'll have to
try to fix it so that I use a USER_SECTION for the vectors.
