/vmlinuz should be a link to boot/vmlinuz-2.0.33
if you, as root:
ls -l /vmlinuz /boot
you should see /vmlinuz, /boot/System.map-2.0.33, /boot/vmlinuz-2.0.33,
should all have the same create time. If not, I'd rm all of those,
and dpkg --install /usr/src/kernel-image<whatever>.deb and check
again. If they still don't match, ask Manoj ;-)
