Why not stick a SPDT switch on each slot on the bus to
switch between the

Go one better. Make the switch a small pushbutton and have some
mechanical protusion on the modern cards push the switch to select the
regulated supply. Old card would not have the protrusion and would
receive unregulated volts.
