Comment 50 for bug 872093

found this workaround in fedora forums, works half by half, e.g. works when sdcard not inserted on boot.

You must add those lines to one of the *.conf files in the etc/modprobe.d folder, I believe it would be dist.conf.

Do this by typing the following into konsole. (substitute gedit with text editor of choice)

sudo gedit /etc/modprobe.d/dist.conf

Then just add those lines:

alias mmc_core tifm_core
alias mmc_card tifm_sd

And save the file.

*If this is the wrong .conf file, someone please correct me.

Hope that helps.
