I just received a reply too - he doesn't know if it works in 09 machine, but they have 14day return if I want to try it. He also said he would be interested too to know if it works, to use it in his personal machine 
Still no word on my payment/order, though....
Edit: the 5770 page now shows 3-14 days delays....might cancel and order from Apple if that's the case
