I think I agree, but smp is not explicitly addressed by the above.  My
example would be: If you have

kernel-2.6.9-42.0.2.EL (kernel-a)
kernel-2.6.9-42.0.3.EL (kernel-b)
kernel-smp-2.6.9-42.0.2.EL (kernel-smp-a)
kernel-smp-2.6.9-42.0.3.EL (kernel-smp-b)

installed and do a yum update, you should end up with

kernel-devel-2.6.9-42.0.2.EL (kernel-devel-a)
kernel-devel-2.6.9-42.0.3.EL (kernel-devel-b)
kernel-smp-devel-2.6.9-42.0.2.EL (kernel-smp-devel-a)
kernel-smp-devel-2.6.9-42.0.3.EL (kernel-smp-devel-b)

This is accomplished for me by having the following in  /etc/yum.conf

installonlypkgs=kernel kernel-smp kernel-hugemem kernel-devel \

Note that the above probably needs some further work, but works-for-me
currently.  IMHO, the "right way" [TM] to do this would be to change the
default for "installonlypkgs=" in yum.

(Any need for multiple kernel-doc versions?)
