If both are attaching to the PCI video device, yes, that won't work. jhb@ has done a little preliminary work on a VGA framework. However, I don't think much progress will be made right now as most developers are bugfixing for 5.3. You can merge the code into mach64 if that works for you. The 'right' thing is an actual driver framework that allows multiple drivers to attach to a common parent. -- Nate
