Hmm, no response. Is this list still alive?

I did some research, and ofwboot.xcf crashes in 
sys/lib/libsa/loadfile_elf32.c, function loadfile().
It tries to load the kernel to address 0x100000.

I've added a line of code to write something to 0x100000 just before the 
READ() call,
with a printf before and after.

The printf before appears, but not the printf after. So it seems that 
address 0x100000
is not writable (or present).

dev /openprom
.properties

reports Openfirmware 4.

So it looks like Openfirmware 4 is not supported. Is this correct?
