My code is correct for the current situation.

We need a rhdMonitor for a panel, we do not, under any circumstances, 
want to set a mode on the panel which it cannot accept. So we need 
information about this panel. No information == no panel, it is that 
simple.

For DVI or VGA attached monitors, it is ok to rely on configured 
information. No real damage can be done, and they all should support 
the modes for early 90s fishbowls anyway, which is the default monitor 
that is attached when no EDID data is found.

I will write up the code to get the panel information out of atombios 
this weekend.
