Hi,
I've been working with ron minnich on trying to avoid the non-free vga option rom for the i915. Personally I target the x60 for now. After porting to the x60 I'll probably try to find a T60 with an intel card in order to port to it.
Right now, I've got the screen that powers on, and even backlight if I add the option rom generated by SeaBIOS(it freezes after it though), however I've only a strange pattern on the screen...and my goal is to have graphics in SeaBIOS and grub(most important),by whatever mean,but without using the non-free i915 option rom.
The code is here: http://review.coreboot.org/#/c/2559/
And the SeaBIOS code will also follow.
As stated it isn't usable yet so it shouldn't be merged.
Denis.
