In the absence of # du -sh /boot/*/ ; ls -l /boot/ that's a help. So you likely have one of System.map, config, initrd.img and vmlinuz in /boot. As long as you have other means of booting the system, you could try copying initrd.img to a backup, and rebuilding it with MODULES=dep in /etc/initramfs-tools/initramfs.conf, and see how much space that would save. If you can still boot successfully with the dep version, then you might have room now to install a second kernel, even with MODULES=most restored. It does make future upgrades a little more tedious.
