Comment(by vbraun):
The relevant paper is Fulton/MacPherson/Sottile/Sturmfels: Intersection
theory on spherical varieties. The bottom line is that, for any connected
solvable linear algebraic group G acting on a scheme, the G-Chow group
(made out of G-invariant cycles) is canonically the same as the ordinary
Chow group. I think I knew this paper at one point, but then obviously
forgot ;-)
