I recently upgraded from 2.6.27-7 to 2.6.27-9 however it did not regenerate my grub boot list to show the new kernel, probably since I manually edited the entries to look neater, how can I do this manually?

*gksu gedit /boot/grub/menu.lst*, clone the -7 entry, and change the -7 to -9. You'll have to change both the kernel and the initrd. Double check that the kernel and initrd you specified actually exist in /boot, and you should be all set.
