I tested the support of the Gigabyte GA-MA785GM-US2H. My main problem was that the integrated radeon doesn't work even with the VGA bios image I extracted from the official bios.
Did you run the VGA BIOS in the coreboot emulator or did you make sure that only SeaBIOS would run it? Note that the default is coreboot, which I think is wrong.
I pass radeon.modeset=0 to access a console and flash my rom to get my old bios back.
OK, so you did have graphics then?
Note that the kernel drivers are often unaware that there exists anything other than what the factory BIOS does, so when testing some graphics hardware together with coreboot you have to be prepared for things not working out of the box. If you fix it, maybe it will work out of the box for the next person.
Any idea on how this can append and how can change my MAC ?
Sorry, don't know about that one.

It's exactly right when not using SeaBIOS. Feel free to adapt Kconfig to only enable the VGABIOS support in coreboot if SeaBIOS is not selected. That doesn't cover the case of external SeaBIOS builds, but I guess people doing that should be aware of such advanced features.

I'm not sure I understand the nuance but yes SeaBIOS was the payload. I
followed the instruction on SeaBIOS page ( http://www.coreboot.org/SeaBIOS#Adding_a_VGA_option_ROM) then I think it's SeaBIOS who managed the VGABIOS. But I didn't know who ran the VGABIOS really (emulator or SeaBIOS). How can I check it ? All my config was default then to answer Patrick, yes my SeaBIOS was built with Kconfig and not externally.

No, only the console worked, the screen froze when xorg started up. I selected a runlevel without xorg to get out of this problem.

I'll try.

:-( but you agree, it's strange, isn't it ?

That's the point. SeaBIOS is the default payload, and the option ROM handling is out of sync with that.
Feel free to adapt Kconfig
