it doesn't say intel centrino duo specifically, it says, "Computers that are running Windows XP Service Pack 2 and that are equipped with multiple processors that support processor power management features may experience decreased performance." I was running sp2, and I had the processor power management.....
I'm sorry but I'm not quite sure what list you're looking at. Can you please clarify?
You have nothing to lose by un-installing it and seeing if it's part of this problem....
