I have been talking with dr oldschool and he has made a vga patch for the nkpatcher method of softmoding the xbox.http://forums.xbox-scene.com/index.php?showtopic=408396
he has made his source code available, however his method only works on softmoded xbox's.
He has suggested to me that this patch method will work with all games, and will even be able to force many games to display in 480p that were only 480i without the need to hex editing.
No it would not have the same issues as ind bios (or other vga bios), because my code is different. I always reset gpu on video mode change. If it were possible, it would be a great use if someone knowledgeable could patch another bios such as the ind-bios or the x2 4981 bios with this patch.
i'd rather not have to softmod an xbox that already has a chip in it. this would be of great use if it works well.
