yum update on kernel switches off of smp

[Jack Howarth]

     I have found that each time I upgrade my kernel in FC4 using
"yum update" that the default kernel is switched from a smp one to
a non-smp kernel. This behavior is different from what up2date did in
FC2 since it kept the kernel type constant across upgrades. Should
I file this bug against yum or the kernel rpm?
