Possibly the latter. The bandwidth of the chip isn't wide enough to
handle both graphics operations and  framebuffer refresh in that
depth. 
You may want to try a lowver pixel clock. 
It is possibly that the chip can get tuned to this mode (by increasing
the memory clock for example) however the driver currently doesn't
offer this feature.
