[coreboot] Any modern server motherboards supported by coreboot?

[Dave Pifke]

If one wanted to use a relatively recent Opteron or Xeon, are there any 
motherboards known to work with coreboot?

I looked at the wiki and there's a lot of red "unknown"s there, the lone 
exception being the ASUS KFSN4-DRE, which is Socket F/DDR2.  And it 
appears to no longer be available other than via Ebay or surplus dealers.
