Number of CPU sockets, or location of SMBIOS on OS X

Question

I would like to find the number of cpu sockets on OS X machines. This information is normally in the SMBIOS on pc's. Newer Intel Macs use EFI but I have read that the EFI does also contain an SMBIOS block.

I therefore appear to need access to the SMBIOS data block on power pc machines, and the EFI, SMBIOS section on Intel macs. Any suggestions would be appreciated.

I don't know any specific API for this (although there probably is one), but at the console, you can run this command and get the answer to be parsed out:
