Part of starting X involves probing the monitor for information about what resolutions, vertical and horizontal frequencies it supports. As there is no monitor connected I believe a default value is chosen for the resolution and refresh rate. It may be that the monitor being used doesn't support this. I'm not sure this is really a bug though.
