It's functioning because a lot of the necessary stuff is loaded into memory. But it likely won't be for long.

If you can find out where the various partitions are, such as from cat /etc/fstab you might be able to run fsck on them and maybe remount them. But if you don't you're going to need to boot this off of some other media (like a DVD of your OS) and do a recovery. Really, if dmesg isn't returning anything, you are probably already at that state.
