Okay, so i didn't do anything wrong here.

$ vidcontrol -i mode | grep 1920
383 (0x17f) 0x0000000f G 1920x1080x32 D  8x16  0xa0000 64k 64k 0xe0000000 
8100k

So this would be 0xc0000000 for me

$ memcontrol list | grep 0xc0000000
0xc0000000/0x40000000 BIOS uncacheable set-by-firmware active

$ memcontrol set -b 0xc0000000 -l 0x40000000 -o BIOS write-combined
$ memcontrol list | grep 0xc0000000
0xc0000000/0x40000000 BIOS write-combine active

... starting X. Nothing changed. I am testing this with youtube videos and it 
is still only "refreshing" every couple of seconds

I am using the vesa driver and NOT uefi

Cheers,
Stefan
