Lately when I've been playing games on my T61, the computer would randomly slow to a crawl for a minute and the FPS drops down significantly.
I would run PC Wizard 2008 and it records the CPU speed at around 300-400 MHz with a Core Load of near 100%. Then a minute later it returns to normal between 800 and 2000 MHz.
This occurs every few minutes only while gaming and I dont know why it happens.

I have a T61 with T7300 and the NVS 140m running Vista x64 and 4GB RAM.

Have you tried turning off aero and using the high performance power plan?

Using the high performance power plan fixed the problem. But it never used to do this in the past when using the balanced plan.
