You have to replace kernel, system kext, appleacpi kext and iopcifamily kext and install AMD webkit.
I followed this step:
I went on insanelymac.com
Downloaded kernel BSA_yos_r6b with system kext, 3 post after (Carlo_67 post) kext to replace....
Then logged in in windows (use macdrive to see, manage and move files in HFS partition) replace all kext and kernel.
Reboot and start a new installation, once in installation menu open terminal and type:
Diskutil repairpermissions "name of partition where you installed osx without quotes"
It will rebuild all permissions, it takes 5/10 minutes... Once finished type reboot..
boot in safe mode and install amd webkit.
Boot your osx with -v -f..... Then cross your fingers (i'll also cross mine)...
if it works fine then just add -f (ignore kernel cache)
It worked for me and for many others....
Amd fx 8350
Asrock 990 extreme 4
16 gb ram corsair vengeance @ 1600
gtx 660 ti (also tryed with ati sapphire hd7xxx series both works)
I can play World of Warcraft with low graphics.... actually really works
Edit: also bsa_yos_r7d worked for me
