I posted on the x1000 forum back in january I think. Couldn't find any details on the whiteheat solution so I made my own, except that mine also conducts. Essentially hacksawing the fins off a pentium heatsink I'd got lying around. After filing it down for smooth edges, the heatsink ended up being 2-3 mm thick if I remember correctly, looking just like a flat rectangular plate of metal. Then using the HP service manual as reference, took the laptop apart, removed the sticky rubber pad on the inside of the video card shield (it had half melted anyway), put some thermal paste on the video card, glued the new flat heatsink to the inside of the shield where the pad used to be (being careful not to block any holes) and put them all back together. I also installed the Omega drivers. It's still working fine after 5 or so months. I did happen to break the zero-force insertion clips on the keyboard and touchpad, but it all still works happily.
As discussed in that forum, not sure if the extra pressure applied by the heatsink helped or whether the fact it acted as a heatsink helped. I don't feel the need to experiment to find out. It works and I'm happy for the moment.
hope it helps
