I am using 6.06, so things may be different.  I have 
/etc/apt/trusted.gpg file that is dated today.  There is also 
/etc/apt/trusted.gpg~ that is a backup dated from 05-08-2006.  If you 
have a backup from before the trouble started, maybe you could revert 
and see if it helps?

You might also check this link:
If there is an updated version of this around, it is supposed to have 
the keys?  Unless I am misunderstanding things.  Good luck.
