Still no reply from AMD folks :/ are there some on this list?
In the meanwhile I tried to dump the BIOS style rom I found yesterday with a
atombios dumper and it does indeed show atombios tables.
So, If we don't find a legacy VGA BIOS for trinity, we could just install this
as fake VGA bios and then let linux to post the GPU. Or if someone likes really
adventures we could possibly build into coreboot an AtomBIOS interpreter and do
the legacy VGA modeset ourself.
