AVR is 8-bit harward architecture while D is designed for at least 32 bits.
Besides that AVR's have from (less then 1) to (a few) kB of RAM so it needs
another standard library with no GC. Guess that's a lot of work, so don't expect
it any time soon even if someone will try to implement it.
I think you'll find that most arduino projects are using a much more capable avr chip, probably avr32 chips.
I wouldn't expect D will ever work well on 16bit microcontrollers, but on 32bit avr's I can't see any reason from my (limited) experience why the toolchain wouldn't just build and work out of the box (at least under linux).
You'll basically need to write the runtime yourself. If you avoid the GC and OS stuff, you can basically stub out phobos, and you might be able to run raw code quite easily...
