Hi Valdis , ,
I had a go with your patch (patched my 171.06-custom with it, pointing the patch towards usr/src/nv.c or similar....) but unfortunately the kernel module build still failed. I'll add my nvidia-installer log to this post to help out.... No need for this to be a priority in any way though
If we can't sort it out in this fashion I'll revisit this idea later.
Thanks for your help so far though!
