Jens has pointed out that power4 kernels are for G5s and the like, which makes
me feel a little foolish! No matter. It's not the first time :-)
I still think the yaboot version issue is going to cause problems so I'm going
approach it thus:
Apt-purge-remove power4 kernel, apt-install correct 2.6.8 kernel!
Run latest version of yabootconfig.
"Kernel (2.4.18) too old ..." (No change there.)
(Check yaboot.conf...
Symlinks take care of kernel image switch.
Boot device identified as 'ultra2:' - should be 'hd:' - leaving alone
though. Boot and root partition correct.)
Reboot...
Nada.
Brief glimse of OSX folder icon and grey screen hang. No yaboot.
Power down. Power up. Boot from CD. Boot into 2.4.18 kernel again.
Change 'ultra2:' to 'hd:' in yaboot.conf. Run ybin (latest version).
[Noticed that initrd=8192. /boot/initrd.img-2.6.8-... is ~ 5MB.
Fine if 8192 refers to KBs]
Reboot...
Nada.
Brief glimse of OSX folder icon and grey screen hang. No yaboot.
Power down. Power up. Boot from CD. Boot into 2.4.18 kernel again.
Leave yaboot.conf as it is and run _old version_ of ybin.
Realise that it is _ofpath_ that is describing the boot device! Doh!
[Didn't make copy of old ofpath.]
Apt-purge-remove (new) yaboot. Apt-install proposed-updates (old) version.
yaboot.conf still as it was. Run _old version_ of ybin (and ofpath).
Reboot...
Success!!! Well, progress!
Sailed through yaboot, straight to new kernel, much quicker boot time, but...
No keyboard. Not even garbage. Cannot login :-/
Power down.
Now what? Kernel keyboard map needs to be passed as a boot parameter somehow.
Can be done from yaboot boot prompt on the CD. What to write though, for an
Apple Pro keyboard? Never got this right in the first place?

The old yaboot (or more specifically ofpath) appears to be the only version
that works for me.

A simple follow-up will usually do.
