After hours bisecting, I found the one-liner which results in the
hang. Now it takes someone else to find out _why_ it causes a hang :)

Subject: [PATCH] Revert "[POWERPC] Don't complain if size-cells == 0 in prom_parse()"
Status: RO
Content-Length: 866
Lines: 24

After hours of fun git bisecting, finally found the commit to revert
to make my PowerBook G3 Lombard boot again. This does not result in
the complains the reverted commit was revering to.

This reverts commit fd6e9d3945ee122eb513ada8b17296d243c1ce5e.
