To allow you to roll back if there is a regression.

I personally keep the previous kernel for a few days to make sure that
everything works properly.

Search for "linux-image"

Don't try to remove the highest numbered entry (that will be the kernel
you are running)

For the remaining "linux-image-2.6.xx-y*" entries, just right click on
them and select "Mark for complete removal".  It will ask you to confirm
that you also want to remove the related restricted modules package as
well.

When done click Apply.  Confirm that you are happy with the changes by
clicking apply.  Wait for synaptic to work its magic.
