Sorry for the long delay to answer.

Thank to your log files, we can see that vt(4) is missing ioctls
compared to syscons, but I don't know yet their purpose. This may
explain the difference of behavior and is something I must study.

Hmmm, unfortunately, I don't know how to help on this, I don't know how
PowerPC works and I don't have the hardware to test...

I hope someone with the knowledge will shine in :)

No need, I understand what you describe. But as the issue is different,
let's concentrate on the other problems first and see if this one comes
back at some point.

Cool, that would be nice!

Thank you!
