Doesn't DDR2 use less power. Having scanned the data sheet, I find only
three major differences:
1. Start up is a different sequence.
2. Lower voltage (=lower power)
3. Shortest burst is 4
Sure, so perhaps it then becomes a hardware cost issue. For embedded.

I don't think that that is needed. Even $100 boards have 128 MB of
memory and a 128 bit video memory bus.
This is more of a space and power issue for embedded. Someone might
want to put a TRV chip on their motherboard. If it's low-end enough,
they won't mind the performance hit; they just need to save power and
space.
