Those two lines are from your new kernel (one for normal boot and one for recovery mode). It's a good idea to leave an older kernel on your machine just in case there is something wrong with the new one. BUT if you are sure everything is fine with the latest one, you can use synaptic to remove the old one, kernel 2-6-27-7.
