I noticed that in fact there seems to be some rubbery thermal pad between the CPU and 
the heat plate (very delicate too ... I put a jolly great tear in it when I tried to 
remove it to see if my CPU was really a P75 or an underclocked P120 ... unfortunately 
it was the former) ... problem is it seems to be only a fraction of the size of the 
possible contact area between the thermal plate and the CPU (granted, the flat area of 
the thermal plate isn't as big as the CPU but that pad isn't even as big as THAT)! 
Anyone got any idea what that pad really is? Is it a good idea to remove that pad and 
hope that the gap so created can be bridged by a good dose of thermal grease or would 
it be better to perhaps soak that pad in thermal grease then put it back? 
Alternatively what material should I use to make a new (more suitably sized) pad?

I'm running Rain at the moment, I'll have a look at AMN Refridgerator though ... I 
assume there's a link to it on your website?

It goes into shutdown even when I've got NOTHING in the PCMCIA slot!

perhaps cooling COULD be better ... I may think about that once summer hits ;-)
