Fedora's way of handling this is pretty sane I think: there's a yum plugin 
that implements a policy that at most 2 kernels will be installed at any given 
time.  When updating, always leave the running kernel installed (since it's 
obviously able to at least boot and provide some functionality), and if 
necessary remove the other one. 

Kernels with special names (ie from the CCRMA repository or somesuch) don't 
fall under this policy (since they need to be manually installed anyway).  The 
"only 2" rule only applies to distro-supplied kernel packages. 

Since distro-supplied kernel releases are typically bug-fixes, there's usually 
not any good reason to have more than two of them installed.
