Before people go berserk with wild optimizations the Linux driver doesn't
handle two optimizations it could (at least if it does then Linus has
cleverly concealed it 8-))

1. Rotational optimization. Given that the rotational latency of a
        good disk these days is no longer irrelevant compared with the
        seek time this would be a good idea.
        
2. Request merging - Multiple requests can be merged into one
        disk operation. This should enable better use to be made of the
        DMA potentially.
