Hmmm, the old kernel should still be there, you just need to select it
when grub starts. Do you remember which kernel was the one that was

You can always see which kernels are available with:
  yum list kernel
(for the Fedora kernels) or
  yum list kernel-rt
(for the Planet CCRMA kernels)

You can install a specific kernel with
  yum install full_name_of_kernel_as_stated_above
if it is an older kernel you might need to
  yum install yum-allowdowngrade
and add "--allow-downgrade" at the end of the yum install invocation...
