The error comes from before X11 I guess.

Sorry for the noise, sure. But when things do not work, I do actually 
start checking the messages.

On the old kernel, here on m iBook, I get:
[    6.016733] pci 0001:10:19.0: Can't enable PCI device, BIOS handoff 
failed.

but then console and X11 work with kernel  5.10.0-6-powerpc #1 Debian 
5.10.28-1 (2021-04-09) ppc GNU/Linux
