  ok, i think i verified that my suspicion works just fine.  after
removing all components associated with that manually-installed
kernel, i just ran update-grub and got:

Generating grub.cfg ...
Found linux image: /boot/vmlinuz-2.6.35-rc4-rday
Found initrd image: /boot/initrd.img-2.6.35-rc4-rday
Found linux image: /boot/vmlinuz-2.6.32-24-generic
Found initrd image: /boot/initrd.img-2.6.32-24-generic
Found linux image: /boot/vmlinuz-2.6.32-23-generic
Found initrd image: /boot/initrd.img-2.6.32-23-generic
Found linux image: /boot/vmlinuz-2.6.32-22-generic
Found initrd image: /boot/initrd.img-2.6.32-22-generic
Found linux image: /boot/vmlinuz-2.6.32-21-generic
Found initrd image: /boot/initrd.img-2.6.32-21-generic
Found memtest86+ image: /memtest86+.bin
done

so that confirms that the update-grub utility just scans for whatever
looks like a bootable kernel and adds that to grub.cfg.

  again, i would do this only for manually-installed kernels, not for
apt/dpkg-managed kernels.
