I dont see I saw anyone advocating removing performance for the sake of
some old 386es.. If there were ever som BIG change that would obliterate
old systems (i.e. a P7/K7 64bit protetected mode) we could either work
around it or just define a new arch (x86old and x86_7thgen+).. Does 4meg
paging break 486es? No, linux only tries to use it on pentiums.. Even if
we didn't adopt new modes and such for compatibility's sake.. Do you think
microsoft would make their OS use it?? The same microsoft who never takes
advantage of new technoligy properly? (I.e. 386es and dos/windows)....
