[lug] weird grub / x11 problem

Background: I'm running ubuntu 10.10. It periodically installs new
kernels and I just got a message saying that the /boot partition was
full. So I nuked some old entries (via dpkg --purge, not simply
deleting the files in the /boot partition) and rebooted.
... go through a few iterations....
I am now consistently seeing three disturbing things.
1) The grub screen shows the 2.6.31-17 kernel and mem test but is
totally nonresponsive to the keyboard. There is no 2.6.31-17 kernel
image still in the /boot partition. (It had been there but was nuked.
2) The /var/log/messages files shows that the grub loader is seeing the
actual kernel images.
3) The system is running a 2.6.31-17 kernel even though there's none
This is happening despite doing a full apt-get install --reinstall on a
later kernel and running grub-update (or is it update-grub) as root.
I can work backwards and realize that it partly works since nothing has
been changed on the /boot partition after deleting old kernel images.
There's no dname entries but the data is still on the disk. This would
explain how an old grub loader could load a deleted kernel image.
But I have no idea why there's a disconnect between what grub is showing
and what /var/log/messages is showing in terms of recognized kernel
images, or why grub is ignoring my keyboard entirely.
