You probably are using outdated lists for readahead. Boot your kernel
with "profile" argument to update it. Then readahead should be better
than preload - preload is better in only some specific situations.

Please also test my prefetching kernel implemented for Ubuntu during
last Google Summer of Code - see http://code.google.com/p/prefetch/
