Dependencies are the things that won't work without the item to be
removed, so yum takes them out too. When I removed the kernel, yum
listed about 20 dependencies. It will take them all out but it won't put
them back when you reinstall the kernel, because they depend on the
kernel, not the other way around. So you have to do it! You can find out
what was removed by looking in /var/log/yum.log (as root).

Actually, I don't use yumex either. I just clicked 'install' on the
popup window advising me of new updates. In my case, what then happened
was that on booting, the new kernel just halted for 2 minutes to have a
think. Then it carried on as normal! Once I reinstalled the kernel the
problem disappeared.

Hope this helps.
