tell me about it :-p

Thing is that it doesn't really depend only on Nokia to get those parts 
done. 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
