I've got a corrupt filesys. How do I check integrity of all installed packages?

OK, here's an other:

Last week I played around with hdparm to optimize hd performance.
Not only did manage to speed up the hd considerably, I also managed
to corrupt my file system. I could still boot after fsck. I can still get up 
kmail to write you this. Most stuff still works but some services
want come up. I know for sure that some symlinks disappeared and I suspect 
that some files are gone or corrupt. 

Is there an dpkg or apt trick to go through all installed packages,  check 
their integrity and reinstall any files that need it?
