The log seems to be missing all of the memory stuff at the beginning, lines with 
terms like 820e and MTRR in them. But I'm buying that it's possible to be 
related to the built in graphics. Does the BIOS give you a way to disable that?

Having run on 16MB system with early Linux versions, I have to say it's only a 
few hundred MB, but... it is.
