It can be found at http://www.tcsscreening.com/files/users/IPDT_LiveUSB/index.html .
The tool is described at http://www.intel.com/support/processors/sb/CS-031726.htm which says: "If the operating system cannot be loaded, a bootable Linux* version is available for you test the processor. Contact Intel Customer Support to get the bootable version of Intel® Processor Diagnostic Tool." I couldn't find the location with Google, and even after-hours non-US Intel chat support didn't know where to find it.
Be sure to monitor CPU temp during tests, especially if you're overclocking.
