Lots of cpu's have more than 2 modes (ie. Kernel/userspace), but unix and linux have always just used the 2. There used to be realtime kernel's that would use the various modes to enforce prioritization, but as far as I know that was never done with linux. Fyi: those realtime systems probably still do that.
