"highly proprietary" is a standard NVidia GeForce Chip minus a VGA
Bios. VBE works fine on it and we have been in discussion with the
xbox-linux people about how to trick it in to working with the Nvidia
windows binary driver. The Windows driver supports everything from the
old Riva cards up through TNT, GeForce[2,3,4}, etc. All we have to do
is add a few hacks to videoprt.sys, the HAL and a few other places and
it should load according to the research I have done. They have not
done this on Linux already because of lack of resources.

I think there might be a few challenges but I have yet to see anything
yet that would require a new kernel.

I think blue.sys will have to be hacked or a new one will have to be
developed but the Linux text mode console works so I dont think it will

one master bootloader.

Yes I hope so as well. If nothing else it will bring more news about
ReactOS which in turn will help us get more developers.
