I discovered that the Makefile in the linked download puts the modules in the wrong place when you make install. It puts them in misc/ instead of kernel/drivers/misc. Once I corrected it, I found that it does work for me -- now I can read SD cards. I believe MMC cards may still not be supported -- I tried one and got nothing in dmesg.
