Okay, so the way I got it working is kinda weird - first, to generate the kernel modules, I had to disable the gpu fermet test. then reaper crashes with 'fractional assert'. Next, I changed it back to enable the gpu fermet test. Then reaper runs without issue. Aggression does not seem to affect how aggressive the miner is, however, so my computer is really not usable while mining. speed does not seem to be much better - perhaps ~2x faster than on CPU alone. I suppose a lot of optimization is coming and various fixes for the weirdness to get it working on all platforms. It also only seems to detect one GPU, unless it's seeing both GPU's as a single OpenCL device? Two kernels appear to get generated, so I'm really not sure what's going on.
