John,
If it was only the initramfs that was damaged, forcing it to be
recreated should solve it ([sudo] dpkg-reconfigure
linux-image-2.6.20-16-generic)

If that doesn't work, try forcing apt to reinstall the kernel. ([sudo]
apt-get install --reinstall linux-image-2.6.20-16-generic).

sudo only needed if you're not root already (Yeah, I know with Ubuntu
you should sudo everything but nuts to that, I always just su!)

Regards,
Cian
