Sorry to break your design, but that was what I had to do to get the RAM

I agree. The patches could be smaller and neater.

However, I cannot hold on to this board for arbitrarily long, since I 
should put it to production use now that Coreboot is working.  I will 
see what I can do to reduce these patches further, if I just find a 
suitable slot of time.
