FYI, ASR isn't supported in the N900 yet. See the N97 for an example of rotating every single element in the GIU. Running at 360x640 isn't so far from 480x800, so I don't see any logic in your reasoning. It may be foreign to you, but I've been using ASR for almost 3 years on Nokia smartphones and loved it. I think once it hits the N900 (and it will if I have anything to do with it), you'll see what I mean.
