I was able to upgrade to the 1.3Ghz Tualatin Celeron running on the Napoli with the Slot-T adapter from Upgradeware. Flash Bios with the Napoli2_2.zip file and made a back-up of the OEM Bios(v2.00) available at [this] site. I received a Slot -T adapter from Kevin Stratton at Stratton Computers. This adapter is very similar to PowerLeap's PL-iP3/T adapter with voltage and FSB settings. Used a retail cpu which was a close fit but does clear the chipset's heatsink. Booted and everything was recognized. The Slot-T doesn't come with a money back guarantee like PowerLeap but for the price it's worth the trade off. Very easy upgrade PnP after Bios flash. Here's a couple links if anyone is interested.

Thanks to Kevin Stratton for donating the adapter for me to test.
