I'm not sure where the value comes from
(don't we use the CPUID instruction?), but
"AP-485 Intel(R) Processor Identification and the CPUID Instruction"
http://www.intel.com/design/processor/applnots/241618.htm
has no such combination but does an entry of
"2nd-level cache: 6MB, 24-way set associative, 64-byte line size."
