Eduardo,

I've narrowed down the problem with the 220R to consinit.c where
OF_getproplen(stdinnode,"keyboard") is called, around line 218.

So I guess there is something in OF_getproplen() that is breaking.

I got rid of it, and booting continued:

then hard hang, had to power cycle.

So there are problems allocating DMA memory, same error on hme0 and
siop0.

If you have any suggestions, I'm able to try them, but will probably
only have access to the machine for another week or so. :/

grant.
