Michael and I have been looking at the SDDR-09 driver.  I could be 
wrong, but as far as I can tell, the sddr09.c code does not grok FAT12.  
It only seems to have generic SCSI commands sent to the USB SCSI emulation 
layer (i.e. it seems to treat SmartMedia cards as generic block devices).  
I believe the actual FAT12 translation occurs in the firmware of the USB 
SmartMedia reader?
