Immedate panic when booting on a 14" iBook G4 1.33GHz

[Chris Baird <cjb%brushtail.apana.org.au@localhost>]

This happens for literally every combination of ofwboot.xcf and kernels
versions, and every installation procedure I can get my hands on.

The system runs OSX10.4 without flakiness, and Debian 8.5 GNU/Systemd
does install. (Although that's the only Linux distro that does.)

Ideas?
