That is probably going to be your best bet. I have added sandy bridge support only as an experiment for GPU... as you have installed your own GPU that process is not occurring. Sandy?Ivy bridge is officially unsupported hardware... and what I am doing to get it to go includes a kernel upgrade (Natty Backport). If myth .25 is just magic for that, then it is the best solution. What I would do, were I you, is load up without any gpu at all, then install the GPU once I got everything going and see how that works out.
