Didj and Explorer MMC Patch
The original source code for the MMC drivers that were released for the LX were not completed but lucky for us there was a patch included that finishes them to a usable state.
to apply these patches just copy them to /drivers/mmc/host/ and type the fallowing
patch lf1000_mmc.c < mmc_patch_lf1000-sdio.patch patch Kconfig < mmc_patch_Kconfig.patch
now when you do a make menuconfig build the MMC drivers as modules then
make -j Number of cpu cores+1 sudo make modules_install
and your modules will be in /lib/modules/2.6.31-leapfrog on your system ready for you to copy them over
