That gives you the Solaris view on the device tree, which is somewhat different. A prtconf -pv gives the openboot view:

Thanks Tarl, that was the output I was looking for. Andreas - sorry if I wasn't specific enough on this, I guess I'm not that familiar with these tools yet :/
Hmmm so it looks like the serial port is connected via ebus on a PCI-based SPARC system. I've so far managed to cross-compile myself a -O0 -g 2.6.32 Linux SPARC64 kernel so I can step things through to try and figure out why the kernel can't seem to write to the console when switching away from CIF to accessing the serial port directly...
Did you try -p or console=prom? Otherwise the kernel buffers the messages until some console handover event, which could be too late.
