I see your point. The user wouldn't will only want to change the resolution at max a couple of times (or not at all) before installing a more dedicated (protected mode) video driver which is capable of changing the video resolutions inside protected mode anyway.
The only thing is, the protected mode drivers will have to be written by someone and you can't expect Nvidia or AMD to start writing drivers for your OS for example. Writing them yourself is an option, but it takes loads of time. Until then, the user will most likely be stuck with slower graphics and 'reboot to get your video mode'.
Thanks for sharing your point of view, I'm seeing it entirely different now.
Kernel video?

When the chance of succeeding is 99%, there is still a 50% chance of that success happening.
Re: Kernel video?
The way Brendan describes it above works fine, as its the method i used in my OS, Brendan does not like it, even though he has not tryed it.
Its simple just not in his text books, so it must be rubbish
.
Anyway here is a demo using that method (NOTE:as theres no IDT set up, some parts are left out that will be needed tobe puting in, in a full OS).
So the demo just switchs between vesa and text mode, every 10 seconds.
