hello ingo,

i am trying to refactor your patch and merge it with the poulsbo enable
(something i wanted to do before merging your patch, but uwe was faster
with committing back then...).

i noticed that you try to disable the prefetching and i wonder why. did
you have any problems with it? we dont do this for any other intel
chipset afaics and i would rather leave it alone/use it.
