I've just tried all SD cards i have here, which are in particular:

Noname 32GB SDHC: works
'PLATINUM' 4GB SDHC: works
Sandisk 2GB SD: works
Sandisk 2GB Micro SD: works

So this seems to be an issue with the specific card - it would be nice 
if you could enable CONFIG_MMC_TRACE, and send me the output.
