Hi, and welcome to the forums!
What you currently have is a "Merom" CPU, upgrades include a T7700 (also a Merom) and Penryn CPUs (up to a T9500). Both types of these CPU's (Merom and Penryn) use socket P and work using the same motherboard chipset (GM965), so theoretically it should be possible.
However, unless the Penryns require some additional thermal IC for proper function - such an upgrade would depend on the motherboard revision, the newest version mobos already carry all hardware fully supporting Penryn CPUs, earlier version mobos may not. A BIOS upgrade would also be in order.
Would be best to get input from a Lenovo engineer on this one for clarification on motherboard revisions and Penryn upgradablitlity on the T61 series system boards.
Hope this helps

Could you please post if you come up with anything on this?? I would be very interested to hear if you had any luck! Thanks.

I believe this was answered on the Thinkpads.com forum a few weeks ago. There was some issue with a "thermal sensing error" using the Penryn CPU. Do a search on Thinkpads.com for this.
