Should I use a seperate functor like this?
template<class T>
struct dereference : public std::unary_function
{
    T operator()(T *pt) { return *pt; }

A a;
boost::bind(&processA, boost::bind(dereference<A>(), _1))(&a);
If you're using Boost.Bind, yes, although it might be better for 
dereference to return a
reference.
...
If the answer is yes, is there a safer and stronger equivalence
of "dereference" in boost?
Boost.Lambda allows dereference.

I've tried with this:
boost::bind(&processA, *_1)
processA(*boost::lambda::_1)
A slight variation should work:

boost::lambda::bind(&processA, *boost::lambda::_1)
