wow, it really worked! :)

applied your patches to the 2.6.35-14 ubuntu kernel, compiled for
32bit, followed you instructions and now I am able to sent you this
mail from working VPCZ with the intel card enabled :)
a lot tricky, at startup the monitor turned on and off a couple of
times but at some point a working gdm popped out...

if anybody could need them I could post the kernel debs (Adam, maybe I
could send them to you to upload together with the existing ones?)

Another interesting finding, looks like that adding all the following
kernel parameters in grub conf (not only the .nopnp) also fixed my
keyboard, maybe you may be interested:
i8042.nopnp i8042.nomux i8042.nopnp i8042.noloop

thanks
fabrizio
