So I reckon you could do it but it would be tricky. From the cobalt patch package "A kernel source tree with this patch will not correctly build a kernel for any other use! You have been warned." I'd do it from an interesting experiment point of view with the view that if it doesn't work then you've lost nothing. Stil it would be pretty cool. Anyone want to send me a RaQ4 to play with? :) Cheers, Graeme
