I am having a similar problem. Also suspected heat problems but it does start sometimes and when in a very cold room i managed to reinstall OSX.
I have taken it all apart and reapplied new pasta on the heatsinks without any difference.
When it does start it works for about 10 minutes, and then slows down to eventually come to a halt.
Temperature monitor says around 34-39C and if opening a heavy webpage it goes over 40C and usually freezes.
I have gotten this powerbook G4 17" 1,67GHz for free since it didn't work properly and i am very eager to fix it.
Anyone found a solution yet, or is it hardware?
