It doesn't exist on the Cyrix. But the 6x86 has a variable sized
paging mechanism (VSPM) that is _partially_ documented - but is
known to behave somewhat differently from the docs and is buggy
in different ways on different chip revisions. No one at Cyrix
is willing to admit any knowledge of VSPM :-).
