  We present some exact scalar potentials for the dimensionally reduced theory
and examine the possibility of obtaining accelerating 4d cosmology from
String/M-theory, more generally, hyperbolic and flux compactification. In the
hyperbolic case, even in the zero-flux limit, the scalar potential is positive
for the 4d effective theory as required to get an accelerating universe, and
thereby evading the ``no-go theorem'' given for static internal space. When we
turn on the gauge fields as source terms at the cosmological background with
potential V\propto exp(-2c\phi), we find eternally accelerating cosmologies
when the 4d space-time is flat and c\geq 1, or hyperbolic and 1<c<\sqrt{2}.
