Ahhh, the "486" is for marketing not to tell us the #cycles each instruction
takes, or what op codes are supported.  *sigh*

However the 386 takes more cycles to eexecute most instructions, so it
is less memory bandwith limited then 486es.  That means a *3 internal clock
is worth more for the integer ops on a 386 then a 486 (but can't help FP
because it is done off chip)..
