Never met the beast BUT as these voltages are usually achieved by a
switching regulator it may be easy enough to change the reference divider to
give a lower voltage. (Same would apply to a linear regulator)

IF the core and IO supply are tied (unlikely) you could be so bold as to
split them and add a voltage dropper and extra decoupling. A silicon diode
plus a Schottky (or probably just the silicon diode) would probably suffice.
Desperate measures but entirely in the spirit of the exercise.
