A while ago I installed 2.6.9-nnnn.plus.c4 (nnnn means version at that time, now at 42.0.2), but I have to boot with the base kernel, as the plus kernel does not seem to work with my Atheros card/drivers. Right now my base kernel is at: 2.6.9-34.0.2.EL and I have this feeling that is quite behind the current rev. I cannot figure out how to get kernel.i686 to upgrade. I can't even seem to get yum or yumex to list the package name for the current kernel rev.
