I suppose there might be theoretical exploits if the GPU memory isn't
protected by the same sort of MMU as the system RAM. But there will
still be some protection, in the same way that a dual UART chip might
provide two serial ports, how much do we worry about the legitimate
user of one port being spied on by another?
