So for the CPU node I have so far:

         cpus {
                  #address-cells = <1>;
                  #size-cells = <0>;

                  cpu@0 {
                          device_type = "cpu";
			 compatible = "Intel,CE4100";
                          reg = <0>;
                          lapic = <&lapic0>;
                  };
          };

This one should match ePARP 1.0. David mentioned threads. I have just one.
No HyperThreading, nothing special. Should I just leave it as it or go
for:
         cpus {
                  #address-cells = <1>;
                  #size-cells = <0>;

                  cpu@0 {
                          device_type = "cpu";
			 compatible = "Intel,CE4100";	
			 reg = <0>;
                	         lapic = <&lapic0>;

			thread@0 {
         	                 reg = <0>;
                  	};
		};
          };
?
