well how about this as a first step. We're getting exception 6. What is that again? Also: is 0x8e41a854 even remotely valid as a bios int? And: 8831:eb60 -- 96E70 -- is that a sensible place for the CPU to be?
It looks to me like the stack is somewhere odd: 774a. Is that right? Where does the stack start out? Finally ... as pointed out, if the VGA bios uses services that coreboot does not supply, it's not going to work. Some of these VGA bioses are very badly written, and this problem can occur.
Just a few questions.
