root fs corrupted: is it possible to check pkg file integrity?

[Joel Soete <joel.soete@tiscali.be>]

Hi all,

Looking for a pb with kernel-2.6.5-pa5, after severall hang, panic, ... 
my root fs was corrupted.
After a fsck i found some garbage into some init files as ppp, 
nfs-common and halt.
I would so now come back to an operational kernel and check the 
integrity of pakage's files installed on my system (a debian sid).
I read quickly man page of dpkg but do not find any option allowing such 
possibility.

Any better idea then re-install from scratch?

Thanks in advance for help,
   Joel
