The kernel panic is indeed there when I compile nouveau in, *after*
some time that X is loaded.

Wild thoughts: I just saw that nouveau calls some ACPI stuff to get
EDID information and, as ACPI is broken on this notebook, could that
be a potential reason for the panic that I'm seeing? (Yes, I can take
a photo of the screen).

I'm simply curious about what knowledgeable people would think.
