I myself have a T8300 2.4ghz. It came out of my XPS M1730 when I replaced it with an X9000. Make me an offer, and maybe we can deal. BUT... just to follow forum rules, let's say US$150.00 OBO shipped??? (please note, I live in Manitoba Canada)
I think skims CPU is a socket 479? and the others are SocketP?
I believe you are correct on my processor. The socket does say 478 though, which is only weird because PGA478 is a Pentium 4 (desktop) and this is definitely a Core 2 family processor. I don't know it came out of e1705 that I do know.
