I use umounted /dev/sdd, with seek (or skip) you avoid to overwrite
the partition table information on the MMC card which it is found in
the first 512 bytes. OTOH, I have, as the default MMC card shipped
with QSB, 8MB of raw data at the beginning of the card, then I have
/dev/sdd1 starting with an 8MB offset from the beginning.

IIRC, u-boot is able to read from ext2/3/4, so you can instruct your
loader to read kernel image from that device.
