You sure about that? It's my understanding that the 4g/4g patch was something that RH wanted to get into the mainline kernel but which was never accepted, so they dropped it.
Hmmm, maybe I haven't built from a stock kernel in a long time. ;->
All I know is that I've seen it in several other distros. I thought the whole purpose of the 4Gi/4Gi model was to give a support/performance point between the 1Gi/3Gi and full 64GiB model.
