In case this is a Linux host...
Though PSN 0 (0) means that even your host seems to have a disabled processor serial number.
I think you guys are missing a key point... the ProcessorID that is returned in WMI is NOT the 64-bit processor serial number !!
The ProcessorID is the return of the CPUID, EAX=1 function (that returns the family, model, stepping, etc). They are by no means unique! The 64-bit portion of the 96-bit PSN is the result of CPUID, EAX=3.
There is a provision in WMI for UniqueID which could be used for this purpose, however I don't know of any WMI provider that currently uses this field. (But that's doesn't mean you can't roll your own).
Data type: string
Access type: Read-only
Processor information that describes the processor features. For an x86 class CPU, the field format depends on the processor support of the CPUID instruction. If the instruction is supported, the property contains 2 (two) DWORD formatted values. The first is an offset of 08h-0Bh, which is the EAX value that a CPUID instruction returns with input EAX set to 1. The second is an offset of 0Ch-0Fh, which is the EDX value that the instruction returns. Only the first two bytes of the property are significant and contain the contents of the DX register at CPU reset—all others are set to 0 (zero), and the contents are in DWORD format.

In case this is a Linux host I assume that Linux disables the serial number for privacy reasons (not sure about that).
Has there ever been a official bug report done concerning this?
