Thanks Jim,
I followed your suggestions and got almost all of the packages back into 
rpmdb. I made a diff between the old rpmpkgs and the almost empty rpmdb, 
edited it and removed the common files, then fed it to yum. The result:

[ovidiu at prometheus ~]$ rpm -qa | wc -l
1002

Mission accomplished.
Thanks again to all.
