Comment (by audun):

 It works, but here's some code that proves it.

 {{{
 from qgis.utils import iface
 from qgis.gui import QgsMapCanvasLayer
 from ftools_utils import getMapLayerByName

 iface.mapCanvas().setLayerSet([])
 }}}

 Now all layers are turned off.

 {{{
 iface.mapCanvas().setLayerSet([QgsMapCanvasLayer(getMapLayerByName("layer1"))])
 }}}

 Now layer1 will be turned on, and the group it was in would be partially
 checked. Note: If there are no layers called "layer1", bug #2543 will be
 triggered.
