I've been searching around for my OS, just to give it a nice
displayresolution. Problem is that I mostly get old ways of how people
used to switch to monochrome or 640x480 screens. But since I'm not using a
screen/videocard that is older than I am, I'm searching a way to switch to some
high screenresolutions like 1024x768 with 32 bit colours and some new features...

Actually I need some good specifications of how to use them young videocards.
I'm just tired of switching in CGA & EGA videomodes, sure they were nice and entertaining until the 90's arrived...

Any idea where I could find out how to use modern equipment without having to use drivers of other OSes?

Video chipset "better" then CGA & EGA & VGA are not standard. That is, you will need to write a seperate driver for all chipsets(S3 , Trident, ...), if you want your OS to run on all computers. Use VESA instead.

Vesa runs all of the higher video modes, and is fairly fast. but never as fast as drivers that talk directly to the card.

Then read Linux src.

You mean xfree86 which is at www.xfree86.org.
