No, I don't use the preload package. You can find the bootcharts here:

Apart from preloading the boot sequence it would be quite interesting,
to preload the desktop startup as long as the DM is shown and the user
didn't log in. kdm has an option to start and stop such a script
automatically. Maybe it would make sense to give readahead a try in this
scenario, too? One just need to find a sane way, to figure out which
files should be preloaded. Maybe loading all files which are accessed in
the first 20 seconds or so...
