Correct,

Quote:

If multiple graphics adapters are present in a system, all of them must use the same WDDM driver. If there are two graphics adapters with WDDM drivers from two different manufacturers, then Windows will disable one of them. The VGA adapter will be enabled, and the second device will be disabled.

MultiMonitor Support and Windows Vista

So even if you did manage somehow to enable the onboard Vista will only use one of them.
