OK, next step: b50f42f0fe12965ead395c76bcb6a14f00cdf65b (powerpc/dma: 
use the dma_direct mapping routines)

git clone git://git.infradead.org/users/hch/misc.git -b powerpc-dma.6 a

git checkout b50f42f0fe12965ead395c76bcb6a14f00cdf65b

Results: The X1000 and X5000 boot but unfortunately the P.A. Semi 
Ethernet doesn't work.
