Dual perpose motherboard

[unforgiven--]

I remember a posted article here on toms hardware about a dual motherboard that had two cpu sockets one of which was a lgga 775 and the other i think was an mobile/atom/ not sure chip but used notebook memory. there was a switch on the motherboard that you could turn on one or the other or both. My old laptop went out and has a desktop p4 chip in it 3.2 ghz w/ 2g memory and i thought of this motherboard but cannot think of the name of it to buy it. any help is appriciated.
thank you

Sounds like DFI's "HYBRID P45 ION-T2A2"
