Using an SD Card for Data Storage

I'm running with an i.MX233 with Linux ltib 2.6.31 and I was wondering if anybody has had any success with mounting a FAT formatted SD Card (2GBytes or less for the drivers). 


The purpsose is to provide bulk storage to the application that can be shared with a Windows system. 


When I look around, I see a lot of suggestions for using "mmcblock0", but that is not an entry in my system's /dev.  When I've tried the other "mtd" devs using


mount /dev/mtd# /mnt/sd


mount -t ext3 /dev/mtd# /mnt/sd


Where "mtd#" is mtd0-mtd4 and mtdblock0-mtdblock4, I get Invalid Format errors except for mtdblock4 which provides a mighty upchuck. 


Any ideas?
