No I mean that the chip modifies it's own VESA BIOS (like one slot is 
reserved for the native EDID resolution of the currently attached screen). 
This is certainly possible, since for a long time, the Linux way to get a 
custom resolution from the Intel driver was to patch it's VESA BIOS. I am 
saying the chip could do it itsself. Would be cool anyways, but who cares 
about some neat VESA features.
