Current MMC stack in Linux would not confuse a MMC/SD card and a SDIO 
device. Basically the intialization and command sets they used are 
different.

Just for curiosity, do you know the version of your proprietary driver? 
You should be able to find it in epivers.h.

A crash log would be helpful to locate the issue.
