Parent article: Adaptive file readahead
The only Problem I have with readahead is when I'm watching a movie in mplayer and I get small pauses when the disk has to wake up from its power saving sleep state...

Seems like it would be caused by a lack of readahead. If the pages were being read in before they were needed they spin-up pause shouldn't cause a stall in playback. Maybe there should be an extra-aggressive readahead mode when disks are set to automatically spin down.
sleep + readahead

For IDE disks you can set the sleep time with hdparm. Perhaps you should
tweak this?
