What do you get if you run "parted -l /dev/mmcblk0"?
What does running "lsmod | egrep 'mmc|ricoh|sdhci'" produce?
It sounds like the reader may be in the wrong mode. But my experience is
with the TI version of the built-in reader. It is also possible that the
ricoh_mmc module is not being loaded.

I'll try those when I get home... I tried doing a modprobe ricoh_mmc
but I'm not very knowledgeable about the kernel and wasn't sure if I
should remove other modules first.Didn't see anything helpful in
/var/log/messages or dmesg.
