IntelSaGopDriver - what does it stand for?

I’ve checked some BIOSes for Asrock P67 Pro3 (quiet old one, but still useful) and found that:
3.25c beta BIOS has it, as long as Ultra Fast Boot option,
Any non-beta (i.e. 3.40, last stable) doesn’t - also I found lack of Ultra Fast Boot option in those BIOSes.

What I want to do is achieve support for higher resolutions in UEFI setup screen - since there is no iGPU support in this one, replacement of Ivb/Snb GOP driver doesn’t have any effect.

What happen if you delete it from rom?
