Well, now that it WORKS here's some info...

Output of partd -l /dev/mmcblk0:
Model: Unknown (unknown)
Disk /dev/mmcblk0: 1024MB
Sector size (logical/physical): 512B/512B
Partition Table: msdos

Number  Start   End     Size    Type     File system  Flags
 1      31.7kB  1024MB  1024MB  primary  fat16        boot

[root@localhost fedora]# /sbin/lsmod | egrep 'mmc|ricoh|sdhci'
mmc_block              18688  2
ricoh_mmc              12544  0
sdhci                  23564  0
mmc_core               52800  2 mmc_block,sdhci


I don't remember ricoh_mmc loading last time... The only thing I can
think of that I did differently was boot up with the media in the
slot... must have made it load the ricoh_mmc module.

Thanks,

Richard
