It really seems like it's missing the appropriate filesystem driver to me. Since you mentioned ext2 and ext3 built into the kernel but not ext4, I wonder if the auto-detect is trying to mount your partition as ext4 type? Try to add the rootfstype=ext3 (or whatever your root FS type is) to your boot line to force it to use the specific filesystem driver you want.
