Hmm, that does not look too promising. Maybe you can get away with some work arounds and some of the Vista drivers
. But it will only be really clear once you tried it.
You could make a "test installation" without activating Windows 7 at first and see what happens. I believe you could operate that way for 30 days. Then at least you can reuse the product key on another PC later in case it does not work out.
