Well, the card is responding, so I think I'll leave my code alone for the
time being :)

That makes sense.

Does anyone have access to the MMCA Manufacturer ID list? I've got an MMC
here that's sending out a MID of 0x01 and a product ID of "IFX064" in the
response to the "Read Card ID Register" command. It would be interesting to
find out who's responsible for manufacturing the MMC controller, if only to
satisfy my curiosity :)

Thanks.
