In a nutshell, Intel PAE36 processors on even AGTL+ are _incapable_ of the combination of both _physical_ and _logical_ addressing to do anything but paging above 4GiB. That's my point.
BTW, there are also issues with Intel's EM64T (IA-32e) processors in PAE52 (Long) mode with "windowing" PAE36 processes on an AGTL+ platform.
Things solved _long_ago_ on the original Athlon, and more formally supported in AMD64 (x86-64), including being enabled on the original Athlon MP with that BIOS-based mode change.
