You would if you tried to update the kernel (thus removing the old kernel 
which is a dependency of the cman-kernel packages).  However, _normally_ 
you DO NOT want to upgrade a kernel - you instead install a new one, 
reboot into it at some time in the future - and only when everything is 
verified to be working do you uninstall the old one.  You often have more 
than one kernel installed at once (I usually keep a UP kernel, an old 
verified working SMP kernel, and the newest SMP kernel which is currently 
being used). Furthermore not every module fits  with every kernel so I 
can't imagine how this could be fixed automatically with the above 
notes...  I guess having some sort of automagical build system in place 
could possibly work?  To be executed at kernel install...  But even  that 
would not always be correct.
