I have OSX installed on my K50IN using this guide (thanks btw), but there are 2 minor issues that I have and I'm wondering if anyone has some kexts or workarounds for them:

1.) After deep sleep and regular sleep audio through speakers no longer works
2.) After regular sleep, the keys for brightness control no longer work (Fn + F5/F6), but after deep sleep they work OK.

Other then that, all is well, just a few nit-picky things. Thanks.
