  I tested above path to IBM ThinkPad600, unfortunately I could not
use Compact Flash Card...
---------------

  I checked in pcic_power@sys/pccard/pcic.c routine. In below code,
re-power pcic with 3.3V. 
----
        /* Some chips are smarter than us it seems, so if we weren't
         * allowed to use 5V, try 3.3 instead
         */
        if (!(sp->getb(sp, PCIC_STATUS) &  0x40) && slt->pwr.vcc == 50) {
                slt->pwr.vcc = 33;
                slt->pwr.vpp = 0;
                return (pcic_power(slt));
        }
----
  But sp->controller was PCIC_I82365 and never set reg |= PCIC_VCC_3V;
  Because PCIC in this ThinkPad is TI1250, but pcic0 is probed
as Intel i82365(PCIC_I82365).

  I think it needs 3.3V for CF card with TI 1250 PCIC or ThinkPad600.
  I added below change, I could attach CF card with ThinkPad600!!
(but this is quick-hack, Please use **at your own risk**)
