Upgrade from 10.8.2 has left me with an unrecognized GPU. Worked perfectly in 10.8.2 with edited id's (0x68f9) AMDRadeonAccelerator.kext+ATI5000Controller.kext. Now, in verbose, both kexts are failing to patch. Any suggestions would be appreciated. Thanks!

Glad we have some others in need of the 68f9 device id and 10.8.3 fix.

curious, when you say downgraded to 10.8.2, how exactly did you do this? is it as simple as just launching the 10.8.2 combo update?

i will keep everybody posted if i find a fix for our 5450s and would like to know specifics for the downgrade process

thanks

Thanks for the kexts, however after installing and GE=no, verbose mode hangs me at "AMDCedarGraphicsAccelerator: **Device is in slot : SLOT--1 **
Getting closer but still no cigar! Here's hoping.... thx.
