The Dwemer ghosts may be spirits from the dead on the war aganist the Chimer, or shades with enough power to reproduce themselves in the mortal plane, like Arniel, not a ghost but a shade...

Also, there's possible that when they touched the Hearth, they DID kmake themselves immortal, and they may be happily enjoying immortallity now... The loading screen also said Volendrung was a dwemer artifact when you actually get it from Malacath.
