There is no equivalent. The driver relies on DDC or EDID data, and 
there's no way to override that on startup.

But, if a monitor is connected but turned off, the monitor should be 
configured anyway. The EDID transmitting device inside the monitor is 
powered by the computer.

As soon as X has started and the output is activated, xrandr can be used 
to set a specific resolution. It can not, however, activate an output on 
which no monitor is connected.
