Are you sure it's not initrd related ? After installing the kernel with dpkg --install i had to run '# update-initramfs -c -k all' and '# update-grub' manually. This is not necessary on debian lenny/squeeze and worked (if I remember correctly) with ubuntu karmic too. Check in your grub config if there is a initrd entry.
