Just recently updated my previous install of OS X 10.8.4 to OS X 10.9 on my Acer and these are the .kexts that I have used. I have it just about 100% complete, just sleep that is causing the problems.

Hopefully you will know what to do with this package when it's downloaded, just install with any kernel extension installer, rebuild caches and then reboot!

Good luck, and have fun! Axl...

- Tutorial coming soon on how to install 10.9 to the Acer V3-571G when I get some spare time.source
