Its already fixed in the stuff I'm working on. Given the list of all
video devices its simply a matter of taking the mmio address and seeing
who owns it. That gives you the PCI device so you now know what the VESA
console is Linux pci_device terms. At that point VESA is attachable to
the PCI device and so it can veto DRI attaches.

I've not addressed what occurs if you get an answer in the ISA window
because for VESA2 allocations I don't think it can occur. If it does
then Jon's code dealing with finding the live VGA route will handle it
for most boxes. (Anyone using VESA video on an IBM summit can fix it
themselves).
