You can remove the non-booting kernel by first running rpm -q kernel to 
list the versions. Then you will want to remove the non-working version 
which is outputted.

Example:
  rpm -q kernel
kernel-2.6.18-1.2784.fc6 - boots OK
kernel-2.6.18-1.2798.fc6 - Does not boot

Next, run the below:
rpm -e kernel-2.6.18-1.2798.fc6

If you want to be sure that the kernel failed because whatever it needed 
was being updated at the time and the old version would have installed 
with all the latest programs installed, run 'yum update kernel' and 
confirm that you want to proceed with the install.

If it still fails, you can remove it once again. Search for an open 
report or file a new report in bugzilla referencing what is on the 
screen when the kernel fails to boot.
