I thought at first that it would, but unfortunately not.
Suppose that the argument is a built-in type...
So, here's try #2 at making property_traits usable
for SFINAE (untested).
I did some little fixes to this (patch to trunk version of 
property_map.hpp attached) and it again passes the graph, 
graph_parallel, and property_map test cases.  Could you please try it 
again with the variant bug cases?
The following tests both compile after I updated two_bit_color_map.hpp to
use SFINAE on property_traits.

#include 
#include 

int test1() {
    using namespace boost;
    boost::variant v;
    int i = get<int>(v);
}

// make sure that it works even with incomplete types
struct S;

typedef boost::variant v_type;

void test2(v_type& v) {
    boost::get<S>(&v);
}
