I would like to echo what Leonard has said. You have all the kernels
installed and you can remove some of them. You should keep 2.6.31-14
and an older kernel (I would choose 2.6.28-15 but I am sure that you
would get more opinions than you have kernels if you asked any Linux
list which kernels to keep).

To get the package names:
# aptitude search linux-image | grep ^i

To purge your unwanted kernels (for example):
# aptitude purge linux-image-2.6.26-7-generic
# aptitude purge linux-image-2.6.26-16-generic

Do not:
# aptitude purge linux-image-generic

Or:
# aptitude purge linux-image-2.6.31-14-generic

Once you have run the "aptitude purge" commands:
# update-grub
whether you are using grub 1 or grub 2
and either /boot/grub/menu.lst or /boot/grub/grub.cfg will be updated.
