Sorry I was little confused about this: the 770 cannot use normal size
MMCs because the kernel does not recognize the MMC until the signal from
the MMC cover comes (when it's closed). So, the kernel would need to be
modified to poll for MMC even when the MMC cover is open before you can
use full-size MMCs; but that would eat more battery as well...

I think SD cards are not supported by the HW.

Yep, the support for partitionless cards should come to one of the
maintenance releases.
