Did you try the patch they have in the Vista 64 listing ? it is seperate to the drivers, they just say install latest driver then apply the patch, The patch makes a reference to compatability mode, their also is another they produced for red alert 3.
I tried applying the patch like you suggested. It didn't work, but the "installation" process was weird. It literally only told me to restart my computer then it apparently were done, maybe it's already inside of the Windows 7 drivers so it doesn't need to be installed?
It was a good suggestion though, I really thought it'd work.
