Because we are dealing with mobile (battery powered) device, the optimal resolution may indeed push towards multiple of 16s if it enables more efficient decoding with CPU and DSP.
I do not know either details enough, but sounds reasonable to have 448 as a vertical resolution because it is multiple of 16.

Would be interesting though to get real world data of decoding 800x448 vs 800x450 in N900 and monitor the decoded session with
powertop
