This is strange - normally yum will not remove the running kernel
when adding a new kernel. Because I do not reboot this machine very
often, I have had kernels installed and removed that were never
booted, because I was still using the older version because I had
not rebooted.

You may be able to get around the dependency bug by using rpm
instead of yum to remove the kernel. (rpm -e kernel-2.6.22.1-32 or
rpm -e --nodeps kernel-2.6.22.1-32)
