Don't want to over-complicate a thread but I've been reading and came across a similar issue a while back when I put a 2011 card in a 2008 MacBook Pro. I had real issues with the patches for unsupported macs, because I wasn't paying attention to what they were installing, it is sometimes too easy to click go and get a result! As @highvoltage12v said, make sure to choose appropriate patches for your hardware, as the patcher detects your system id, not the hardware that is actually installed. For me, to undo whatever needed undoing to get a newer card working, required a clean install.
