The dbpedia RDF specifically links to the Freebase data via an  
owl:sameAs  predicate.

The reason you see more RDF assertions at http://dbpedia.org/page/Bobby_Rahal
than at  http://rdf.freebase.com/rdf/guid.9202a8c04000641f800000000031a897
is that dbpedia is exporting more raw data such as wikipedia  
categories and all the
infobox properties at a low level.

Freebase only has the data that has been specifically hand mapped to  
freebase schema.
For example, because we dont have a racecar driver type yet, we have  
not mapped available data
like   p:firstWin • 1982 (xsd:integer)   into freebase data.   Over  
time we expect more of
this data to get mapped automatically into corresponding freebase types.
