Me! I couldn't manage it with the existing firmware and
'http://www.netbsd.org/Ports/macppc/faq.html#ofw-bugs' states
something like 'If you have a mac with Open Firmware 3.0 or higher,
you might be able to download a new Firmware for your machine on the
Apple Software Updates web site.' That's what I did then...

Sigh, is there a way back (to a working firmware version)?

At the moment my tibook is completely 'broken' because it no longer
activates the display after booting!? Even Command-Option-P-R doesn't
change this misbehavior. (Also an 4.1.8 firmware upgrade effect?)
Anything I can do here?

Hmm, I was too impatient with my existing firmware, I guess.

But, as I read, you upgraded your tibook firmware to 4.1.8, too!? ->
What are you going to do about that?

At least, I'm not alone.

What is the 'right' firmware for a tibook? And how/where to get it?
