Sorry about the trouble.  This error is due to a combination of two 
factors.  We signed the previously unsigned packages, but forgot to 
repocreate the metadata again.  Your yum grabbed the unsigned metadata, 
which didn't match the checksums on the newly signed packages.

Unfortunately everyone that grabbed metadata prior to signing will need 
to clear their yum cache.   Even though today's rawhide is consistent 
between packages and metadata, everyone will need to use "yum clean 
headers metadata" in order to proceed with further updates.

I consider this to be a bug in yum.  Once we accidentally pushed an 
unsigned package in FC4 Updates.  When realizing the problem Sopwith 
signed and re-pushed it, but anybody who had already downloaded the 
unsigned header forever was stuck being unable to upgrade.  Because we 
had no choice, we had to rebuild the package so yum would re-grab 
headers and continue updating stuff without manual intervetion.
