I checked AMD website today and found out a new CPUID Spec. Rev. 2.34 was just released: http://support.amd.com/us/Embedded_TechDocs/25481.pdf They have added CPUID 0x8000001d and 0x8000001e to detect topology, it seems. Also, CPUID 0x80000001 %ecx bit 22 (TopologyExtensions) tells you whether the above CPUID functions are supported. Interesting...
