Recently a new kernel for Intel and AMD platforms was set loose into the wild.

The StageXNU kernel is currently in an early beta, but it is already garnering positive reaction from within the OSx86 community - particularly those with AMD systems.

The kernel (9.4.0) offers SSE2 & SSE3 support with working sleep and shutdown functions on AMD machines, as well as preliminary speed-step support (CPU throttling) and will report the correct amount of cores within Apple System Profiler. Generally the new kernel has been said to make systems feel 'snappier'.

Please remember that this kernel is in beta and your mileage may vary. Development is rapidly continuing with future optimizations and features being steadily introduced over a period of time.

Thanks to community member bhast2 for the information. The kernel can be obtained from the Leo4All forum (requires registration).
