Remove old kernels

If you go to System→Administration→Synaptic you will find the kernels
and their headers are installed as packages.

To make them easier to find inside Synaptic click on STATUS in the
lower left then you can filter by INSTALLED packages above, type
something like 2.6.31 in the quick search box and they will appear.

There are 3 packages for each version number, Image, Headers, and
Headers-generic.   Click on the yellow boxes and choose Mark for
Removal, then click Apply when you are done.  No changes are made
until you click apply so you can look around without breaking things.

I would recommend keeping one extra version as backup so that you can
select something else at boot if you current kernel ever stops
working, ie if -19 is your main kernel then keep -17 around and remove
the others.
