Um, yes they can. You just need to include the dtb in the zImage wrapper. I've booted Ebony with Openbios using David's patches and Bamboo with PIBS using my patches (which are based off David's patches). What I think you mean is that there is no translation from a bd_t (using older u-boot for example) to a dt in the wrapper yet. But that is what Scott's cuimage patches are for. josh
