sorry, don't know about limitations of u-boot from 2008, I'm using Qi for few years already... > >> Ahh this is new.

This SD-card has been > written and of course read by my card-reader of my linux system Some cards need longer rootdelay as you have tried (with this kernel you can also use rootwait). Some cards need different clock see https://docs.openmoko.org/trac/ticket/1743 but don't know if this is the case.. make sure you have right partition type set and that filesystem there is really ext2 not ie ext4.
