I've read on the Volt forum that if you put it in cruise and L, it will then hold a constant speed downhill.
Of course, the conditions have to be conductive to using cruise control downhill.
Skipping cruise control use, you could also then use / feather the gas pedal to lessen the 'engine braking' provided by L. Won't hurt anything, you're just telling it to not regen so much by using the gas pedal.
Also, they say that you can tell when you're off the regen braking by the little green ball. When the spinning leaves in the ball go away when braking, you're getting into the friction braking.
