Tested all of your three new Mountain Lion kernels. At first, all of them would return a kernel panic, regardless of the flags used, backtracing a "faulty CPU", but i found out it was the SleepEnabler.kext. So, from the start, the kernels break the only kext that allows AMD machines to sleep/wake properly since 10.7.x.
Disabling the SleepEnabler with pmVersion=0, the boot hangs at Kernel=LP64 with both the ssse3 and the FX kernels, regardless of the flag. With the sse4.2, the system boots to the desktop, but the new kernel breaks my graphics: no QE/CI and heavy glicthes in the Dock, the Desktop, Safari and other applications (pic attached). This new kernels also requires the patched Corecrypto from the first page of the thread, and as a suggestion you could include it with the files.
All in all, i cannot recommend this new kernel for all AMD users running 10.8.3, specially if they use a non-FX CPU: they should stay with AnV's and_kernel for a while. But i'm confident, Bronzovka, that you'll come up soon with a revised kernel addressing all these issues, making it as stable and reliable as your latest Lion kernels. For now, thank you very much for your hard work, and keep'em coming!
All the best!
