The problem with supporting new devices is, without a corresponding
addition to binutils and GCC, it could not even be compile-tested in

Why that?

if you want code for, say atxmega128a1u, why do you need -mmcu=atxmega128a1u to be supported?

Just compile -mmcu=avrxmega7 -D__AVR_ATxmega128A1U__ and follow the description in the avr-gcc Wiki.

That way you get max independence from the compiler and the assembler.

An AVR Libc installation would bring crtx128a1u.o and iox128a1u.h but that's no problem.
