Just to be sure I would check that the kernel is actually installed,
"rpm -q -a | grep kernel" and see if it is there (should be, of course).

Strange, do you remember if there were any error messages when you
installed the kernel? If the package is installed but there is no entry
in /boot/grub/grub.conf and no initrd it means that the post install
scripts somehow failed. There should have been messages printed. Maybe
because you are (apparently) running RedHat Enterprise things are
different enough that the kernel does not complete its installation
scripts. 

One way to find out for sure would be to erase the kernels and install
them paying attention to the postinstall messages (if any).
