This is why Fedora adopted the pre-release versioning scheme that we
did:

http://fedoraproject.org/wiki/Packaging/NamingGuidelines#PreReleasePackages

In the Fedora scheme, this would be

0.%{X}.%{alphatag}

Or, in your specific example:

kernel-2.6.22-0.2.rc7.git1.fc8 vs kernel-2.6.22-0.1.rc7.fc8

[root at dhcp-32-74 ~]# /usr/bin/fedora-rpmvercmp
Epoch1 :0
Version1 :2.6.22
Release1 :0.2.rc7.git1.fc8
Epoch2 :0
Version2 :2.6.22
Release2 :0.1.rc7.fc8
0:2.6.22-0.2.rc7.git1.fc8 is newer

Note that for this to work, you need to increment %{X} upon every new
package.
