[Solved][GRUB/ATI] Video problem

Hi all.
I have a Radeon HD 6670 (Turks XT/r600)
When I boot arch linux live from USB everythink works ok.
But after install I have no video.
System boots > shows grub > shows systemd things > screen blinks and all black.
After some self research, I found "gfxpayload=keep" on grub parameters and change it to "gfxpayload=disable", then F10 and everything works great (video/X/VDPAU/3D...)

Why it hapens and how can I permanently set this disable on grub?

[EDIT]
Some PC, some instalation, with on board HD4250 (RS880G) video works with gfxpayload=$ANYTHING
[EDIT 2]
You can change gfxpayload on /etc/default/grub

You can change gfxpayload on /etc/default/grub

After which you run '# grub-mkconfig -o /boot/grub/grub.cfg' and the changes are saved.

Yeah, solved.
But I'm still trying to find out why this BUG happens.
