Well, we can get the kernel part done by just cleaning up and porting the 2.6.28 drivers to current mainline, but in case of e.g. SGX we still miss the xorg driver and I don't think that'll be released any time soon. Another problem is that the bootloader believes it can pass all the obsoleted OMAP TAGs to kernel and the 2.6.28 kernel depends on those, maybe that can be worked around. I don't know whether kernel simply drops invalid TAGs or not... Good work anyways... At least it's now documented ;-) PS: BTW, CBUS isn't really necessary for n900 and I have almost 40 patches cleaning that up pending in this mailing list :-p -- balbi
