I see the exact same behaviour with my tripple head setup (Radeon 9600pro for 
2 heads and another MGA Mystique 220 for the third).

Though I thought before, that this was because of a currently missing feature 
(whatever that was, I do not remember, but I read somewhere, that smth is 
missing) in the radeon driver.
