Kevin - I've for years been removing the old files manually.

What I do after the 'uname -r' is 'rpm -q kernel'.  That gives me the 
full name of the kernel that is not running.  Then I do 'rpm -e ...', 
specifying that obsolete kernel_full_name.  I begin to finish up with 
'find / -name ...' (where ... is a unique string extracted from the full 
name of the deleted kernel).  Typically there will be leftover files 
within /versions/pristine/883 .  I manually delete those.  [In my 
opinion, the principal nand-space user is the leftover /lib/modules/,,, 
from the previous running system.]

Of course, if the new kernel you installed did not come from a 
fully-functional rpm, then little things (like drivers) might stop 
working.  If you wanted to no longer use the new kernel, but had deleted 
the previous kernel, you couldn't go back (e.g., by manually changing 
the pointers in the /boot directory <as used by OFW>) -- you would need 
to do a complete re-install.
