You'll eventually have something to test, this part was just 
infrastructure and didn't change anything at all.

Yeah, nothing has changed yet for your case. What should change your case 
is the thing Yinghai is working on with the "late add of e820 data to the 
resource tree".

His earlier version already worked for you, didn't it? We're really now 
just finalizing details (in fact, "insert_resource_expand_to_fit()" is 
just a helper function for a detail that may not even matter all that 
much).
