I think the reason is that Red Hat is following Linus's lead on this:
If you want more than what the base architecture go to 64 bit. While
you can get 4gb on a 32 bit kernel, there is a non-negligible
performance hit and a lot of odd things seem to happen that are not
reproducible.. but thought to be due to the various hacks one has to
on the chipsets to get it to be more ram than it is supposed to.
