SD is a one-card-per-bus arrangement; SDIO too, as I understand.

MMC supports multiple cards per bus, at least the older/slower
versions of MMC.

So absent external hardware like a bus switch letting you talk
to either an SDIO device *or* an SD card, I don't think you can
do that.  (And such a switch would likely interfere badly with
SDIO interrupts...)
