Good idea, but async i/o is generally poorly supported.
Async i/o is stably supported on most *nix (apart from Linux 2.6.*) plus Windows.
Guess it would be still worth it, since one fine day 2.6.* will start supporting it properly too.

Err, readv allows you to split a single consecutive read into multiple
buffers. Doesn't help at all for reads on widely areas of a file.
Have a ncie day,
