The main goal of this isn't just to get chameleon to the native resolution, it's to have native resolution in MacOS since the first boot after installation (and maybe during installation), before you've set up GraphicsEnabler, messed with your kexts and all. And to keep native resolution if you have to disable GraphicsEnabler for a while... To have native resolution, no matter what.
I don't know, if I understood you correctly, but is it also possible to have an unstretched (bios) boot logo with this method? The resolution of the bios boot splash is 800x600 and is transmitted as a 800x600 picture to the LCD monitor, where it finally gets scaled up to fill the screen. However, I'd prefer my LCD monitor not to stretch up the picture, but to center it, leaving it at its native resolution and showing it really sharp. Telling my graphics card to send out 1920x1080 pics, (so my LCD display doesn't stretch it up) using this method, will it do the job?
//Edit: I'm talking about the hardflash method.
//Edit2: I thought about it last night and I came to the following conclusion: I need the GPU to tell that he'll do the upscale with an unstretched, centered picture, so the display will just show the received 1920x1080 picture from the GPU. So, the GPU has to do everything. Any ideas how to do it?
