Notice that using any kernel older than 2.6.14 for firewire disk usage is kin
to bring only disaster, as it consistently died when doing larger firewire
disk transfers. 2.6.14 is fixed in that aspect. Not sure if yaird |
initramfs-tools will help here.

Ah, so you compile your own kernel to make it work, hardly the best way. What
you need is firewire support in yaird|initramfs-tools.

Can you file a bug report against yaboot-installer with this ?
