Headless would be last resort. If possible I would like to have a
monitor connected to the system (either mainboard or graphics card)
and have a desktop there. I don't need video while booting (but I
would appreciate it, of course). I understand this is possible
depending on the GPU. When you say a system with a framebuffer you
mean any system with linux User Mode Setting should work without
propietary VGA BIOS ?
i think what marc said means these mainboard which has framebuffer driver.

Do you mean deblobing linux/X graphics drivers is a continued area of development
or supporting IGP + graphics card in coreboot (if it needs some speacial support
by corebbot) is a continued area of development ?

I don't have a prefered board (yet). I was thinking of picking one
of the few that people has shown some interest in here in the list.
That might be best for me as a newbie as I wouldn't be alone even
if it is not currently supported yet. I'm not sure if it would be
best for the project (having more that one test instance for the
same board ) or it would be best to have as many different boards
to test as possible.
the 780 mainboard which coreboot support now is mahogany. I am trying to porting a few more
mainboard as GSOC project. the mainboard i choose at this moment is
1)Shine,2)Tilapia,3)Gigabyte GA-MA78GM-S2H,4)ASUS M4A78-VM 5)Colorful C.A780G X5.
i am aslo checking if i can order an Jetway PA78VM5-H which Scott have much interests. You can
choose one of them or the other 780 mainboard.

Ok, I can wait, I guess. I can start by the OS, test flashrom
with the propietary bios, etc. and handle coreboot proper later.

I had read something (either in coreboot wiki or from some link there)
but I no longer find it. I thought SPI could be socketed or soldered.

In goals, we have a lot in common, I'm just less active pursuing them.

Are there ? I've been looking at the supported mainboards and found
few that I could buy currently in a shop and are relatively
powerful. I'll look again.

I've already wited quite a lot, and my current laptop is falling
apart. So I may buy soon, but I may install coreboot later (I
understand buying before getting support may be risky). I'd like to
buy something with coreboot preinstalled, but that may be the next
system I buy after whatever I get now. In your products page I've seen
a couple of servers with coreboot I might get, but they're a bit
expensive for what I was thinking.
Thanks for your help.
