Hum, that's a side effect of enabling the new interrupt tree parsing on
all machines. Well, that's more or less my fault: the pmac_newworld
variable gets set to 1 on CHRP, thus enabling the new interrupt tree
parsing on them.

A better fix would be to only enable pmac_newworld on pmacs. (But still
keep the interrupt tree parsing for chrp since it's basically a chrp
thing that Apple implemented in newworld machines).

Note that this problem may be present in recent 2.2.x kernels too.
However, a subtle difference in 2.2.x is that _machine may not be
initialized yet when finish_device_tree() is called.

I'll look into those today and push fixed to both bk trees.
