if you are using xorg 6.8.x turn off mergedfb (option "mergedfb"
"false").  this will cause crtc1 to drive both outputs.  if you want
separate resolution and/or refresh rate on the lcd and vga port then
you'll need to set up mergedfb clone mode and probably enter the hsync
and vrefresh for the projector in your config.  see the radeon man
page.
