I implemented this according to the document Pam Huntley pointed out
several months ago:
  http://www.pc.ibm.com/qtechinfo/MIGR-45120.html

I should have done that times ago but never found the time to do so.
Some weeks ago I implemented it in C for integration to the dmidecode
project, and I converted the code to Perl today.

This detection method is expected to supersede the two other ones we had
until today (DMI and ACPI). Three significant advantages:
1* Detection will be more simple with a single method.
2* We won't rely on dmidecode anymore.
3* VPD is more precise and efficient since it's aimed at IBM systems.
   We'll be able to start a blacklist and/or a whitelist.

I'd appreciate some of you give a try to sensors-detect now. If the VPD
detection method if confirmed to work, I'll drop the other two methods
soon.
