Alas, it doesn't.  While this file is compiled four times for the
various devices, this is done using the generic device model name
(-mavr2 etc.), which doesn't cause any <avr/ioXXX.h> to be included.

Maybe we should add fallback definitions for SP/SPL/SPH and SREG at
the end of <avr/io.h>?  Their register numbers are (so far ;-) the
same across the entire AVR device line.  I agree with Ted that
hardcoding register numbers inside source files is just evil.
