There are several "Long Modes" -- some are not yet implemented.

Dude, I'm _not_ the only person who refers to it as PAE52 or PAE 52-bit.

AMD and Intel _both_ refer to both PAE 52-bit and PAE 32-bit as just
"PAE" for short, because the bit that enables it is the same.

Some just like to differentiate.  I do.  I'm not the only one either.

It is mathematically impossible for someone who makes more than you
to be anything but richer than you.  Any tax rate that penalizes them
will also penalize you similarly (to those below you, and then below
them).  Linear algebra, let alone differential calculus or even ele-
mentary concepts of limits, is mutually exclusive with US journalism.
So forget even attempting to explain how tax cuts work.  ;->
