ok. I'll try to do that.
How does diff work ?
I don't know the correct options to create a diff file...

Maybe. Exiting X quite often hangs the system completely.
I don't know if that's our fault or an error in the glint driver.
I haven't had any crashes when I only use FBDev, but maybe that's just luck
as I use glint most of the time...
Also: the color in console sometimes is wrong after exiting X.
Switching consoles brings it back to normal.

???
I can't find any option for that...

I have managed to remove these errors.
I'll try to make a diff...

basically I added the line
bus->resource[1] = &pci_mem;
to the end of apus_pcibios_fixup_bus(...)
(as done in chrp_pci.c)

I also moved the request_resource code that you added up to
apus_pcibios_fixup() to make it look more similar to chrp_pci.c, but that
wasn't really needed, I guess.

Yes, don't know where it came from. It's not there anymore...
