Had this problem when I installed the latest kernel in Jaunty. At the end of the install I accepted the default of keeping the existing Grub menu. Big mistake. update-grub would not add the new kernel to the menu.lst. Spent 2 days trying various solutions proposed in forums.
Finally found a simple solution. Remove /boot/grub/menu.lst. "sudo rm /boot/grub/menu.lst" It will then offer to recreate a new menu.lst. Now run "sudo update-grub" Reboot and it will load the new kernel. Confirmed with uname -a Only odd thing is you will need to hit escape quickly to see the entire boot list, but that's OK as it saves a step and boot is faster. If you have a duel boot and need time to select a different kernel or OS there is probably some way to modify this and set a time out.
