Hi Sebastian,
yes I'm using an AT91SAM9G20-EK Rev.c with two SD slots.
I used slot a but I think you just have to init slot b.
in PatchV3 you can read:
>at91_mci0_hw_init(int slot, int bus_width)
>switch (slot) {
> case 0:

> case 1:
So I think you just have to call at91_mci0_hw_init(1,4) for
slot b.
bye
Konrad
