OK sounds like that's the issue then, hopefully moving the dtb around
helps.

If the SD card is not detected with appended dtb either, the card
voltages may not be supported. I believe Rajendra mentioned in some
mail that we're still missing some voltage settings for the DT case
for omap_hsmmc.c. In that case the card should work for the non-DT
booting though.
