Yes most of the Intel oproms (vga bios blobs) are publicly downloadable 
from the Intel website (just look for the developer drivers). I think we 
should have a section in the tree for the blobs. I think the only 
discrepancy Intel has is they do not want hacked/cracked copy's of their 
blobs re-distributable...
