Debug it as a standalone application (i.e. use a relocated .text
instead of .bootloader section).

Alas, on the ATmega128, you'll run into the additional problem that
GCC doesn't emit the correct DWARF information above 64 KB (has been
discussed here).  Maybe COFF works better in that case, I don't know.

That will for sure happen, perhaps even very soon. <grin>

Never trust an operating system you don't have sources for. ;-)
