I'll try this.

However, I have a memory of ducument that says somthing about
the value which you use port# of "2" like:
		switch(x){
		case PortVGA:
			vga->edid[x] = snarfgmedid(igfx, 2, 0x50);
			break;
in snarf() function. 

The document has a table which says individual chip has a different 
port number for a same PortVGA...
My memory goes bad these days, however, I think you can find it
from Intel's support site which was a short paged one.

I may be wrong, however, the behaviour suggests it, I suppose.
