Okay, I did some elementary research and it appears it was never
adopted in the stock 2.4 kernel.  Although 2.6 seems to have been
designed for it -- although I see the issues you were talking about,
largely when user >2GiB.  I'd be interested in finding out if they have
the same issues with the 64GiB mode and formal PAE36 paging.

Anyhoo, my apologies on that _poor_ assumption.  Given my lack of
exposure to stock kernels, I should have kept my mouth shut.  I don't
know why I didn't put 2-2 together.

But it should be noted that it's no longer a Red Hat-only thing.  I've
seen several non-Red Hat (or long-gone Red Hat forked) distros who
are using it.  I should have made my responses in that context.
Again, my apologies for that.
