Well,
After alot of trial and error, I think I may have found the issue. I still
don't know how to fix it yet though. It appears to be something with IRQ
Routing. I think the graphics is NOT supposed to have an IRQ asigned to it.
In the past I have seen bios settings that you have an option to asign an
IRQ to the graphics or not. If you look at lspci from the proprietary bios
everything has an IRQ but the graphics device. I setup the irq routing and
PIRQ's just the
way the proprietary bios is and it boots ok (no errors from VM86) but in
Linux it says
everything is IRQ 0. In the current coreboot code the IRQ routing is setup
the same as the RM4100.
Can I just remove the graphics device in irq_tables.c? Or will that really
screw up the routing?
I have three different vga bios's and they all do the same thing.
