Your image does boot for me - after changing features on filesystem.
http://dev.laptop.org/~quozl/y/1gHh5m.txt (dmesg)
dumpe2fs of your image filesystem features; has_journal ext_attr resize_inode dir_index filetype flex_bg sparse_super large_file huge_file dir_nlink extra_isize metadata_csum, and flags; signed_directory_hash.
dumpe2fs of my image filesystem features; has_journal ext_attr resize_inode dir_index filetype extent flex_bg sparse_super uninit_bg dir_nlink extra_isize, and flags; unsigned_directory_hash.
Our OLPC OS builder uses "mkfs.ext4 -O dir_index,^huge_file", from e2fsprogs 1.42.5.
I'll look at the microSD card errors; by trying another one.
Fantastic progress though, thanks! Wish I were a full time kernel developer, but so much else to do now.

Let me know what you need there; with a patch, and if it isn't too extensive I could spin a new build. We're not producing these models, so I don't _have_ to keep the factory test code working.
