Ok.

It is the same rom I was using with the GTX660. No changes.
Seabios was starting fine, menu quickly appeared after coreboot init was done.

I don't have enough knowledge to interpret cbmem output but I was wondering 
if something was wrong before Seabios payload execution ? Is the Ati card detected ?
Only Aspeed VGA controller seems to be recognized.

Also, what is meaning of this :

"link_width=2, lane_mask=ffPcieLinkTraining port=c:lc current state=2030506" ?
