Confirmed, but I'm not sure the code is valid. icc7 says, for example:
g/x> icc -c -Xc -ansi x.cc
x.cc(1): error: a parameter of a template template parameter cannot depend on
the type of another template parameter
template <template <typename U, U* p> class T>
^
x.cc(4): error: a parameter of a template template parameter cannot depend on
the type of another template parameter
template <template <typename U, U* p> class T>
I think we need some language lawyer here...

I cannot find such a restriction in [temp.param].

I beleive the code is well formed. The EDG 3.3 frontend accepts it
in its pedantic mode.
