mycroft ec14ab4b89 The Ricoh power hackery is not reliable -- many cards just do not have the 
voltage sense wired.  So, disable it and force the card to 5V by default.
Also, recode the hack to use the "direct Vcc" feature of the chip, letting
it manage the voltage directly, as this is supported on both the 296 and
396.
