Here's the command I'm using and the output. I put a debugging statement in sd_init_card() after the for loop (HJS:).

Err, well, that's weird. I have to admit I can't even guess whether it's trying to read the right slot. Could you please:
1/ add a #define DEBUG at the top of drivers/mmc/atmel_mci.c 2/ get the output of mmc init (0 or 1 doesn't matter) for both CONFIG_ATMEL_MCI1 and !CONFIG_ATMEL_MCI1 (with the SD card staying in the same slot, of course) 3/ In the process, add a debug printf in the mci driver displaying the value of MMCI_CR (you'd get that by calling mmci_readl(CR))
I'm sorry I can't help you further. Unfortunately I don't own such hardware, and this kind of thing is rather hard to debug remotely.
