Comment:

 The third card slot on the Via demo board works in SDIO mode.  Here's what
 I did in OFW:

 * Set D17F0 Rx51 bit 7 to 1, thus disabling the card reader block  (ok
 8851 config-b@ 80 or 8851 config-b! )

 * Set D17F0 Rx97 bit 2 to 0, thus muxing the slot pins to the SDIO block
 instead of the card reader block  (ok 889f config-b@ 4 invert and 889f
 config-b! )

 * Set D12F0 Rx99 bits 2:0 to 010, thus enabling 3 SDIO slots (ok 6099
 config-b@ f8 and 2 or 6099 config-b! )

 * Patched OFW's sd/disk driver to use slot 1 instead of slot 3 (ok dev
 /sd/disk patch 3 my-unit open dend  )

 * Inserted an SD card into the multipurpose slot

 * Accessed the card with the OFW driver, for example   ok .partitions
 /sd/disk

 It worked with no surprises.
