I've just tested with PowerMac1,1 and here's what I got:

DEFAULT CATCH!, code=700 at    %SRR0: ff831434   %SRR1: 00083030

So probably you are right...

I've noticed that there's a big size difference between the old working (ofppc) 
ofwboot, and the new:
57252 ofwboot.good
53984 ofwboot.new
Is this due to better optimization done by the new gcc?

Also, now ofwboot has one new section added:
  [ 8] .gnu.attributes   LOOS+ffffff5    00000000 00cfb8 000014 00      0   0  1
That's probably unrelated, though.
