It's interesting no compiler I know of currently support it.
C++0x draft 14.3.2 [temp.arg.nontype] paragraph 1, allows non-type
template argument to be a constant expression
that evaluates to a null pointer value or null member pointer value.
Quick searching tells me this change was made in N1905(2005-10-19).
