The command you gave, results in:
thomas at maus:~$ ls -lah /boot
total 39M

I also found on the net a "1-command solution":
http://tuxtweaks.com/2010/10/remove-old-kernels-in-ubuntu-with-one-command/

That command is, however, WAY beyond comprehension.
But .. if it works (have not tried yet), I could copy it in regular 
intervals from a text file to run it.

Then again, as I asked before, should all this not run "automatically"???
Where any update overwrites old, no longer used files, so that there is 
no need to do all this stuff manully.

I cannot remember ever having been asked for by other Linux flavors to 
free room on /boot ...
