Re: ureadahead (not running?)
The kernels you have won't be making the pack file used by ureadahead. You can either have it generated by installing a version of .31 from a PPA (I can't remember where, I can look if you want, have it running at the mo), or wait until the next kernel update (which shouldn't be long seeing as ureadahead is in the repo).
