Using the current Wine code (without this patch), modifying the modes
list so that a particular refresh rate appears first in the list is
the only way that I can see to specify a default refresh rate for a
given resolution.  This is because the current Wine code chooses the
first mode that matches the resolution if no refresh rate is specified
even if there are other modes with the same resolution but different
refresh rates.

I think what you're saying is that Wine's current behavior (pick the
first mode with matching resolution) does not necessarily reflect
Windows' behavior so testing needs to be done to see what algorithm
Windows uses to determine the refresh rate when it isn't specified.
Correct me if I'm wrong.

This test definitely needs to be done.  I will hopefully have time in
the next few days but if someone else beats me to it, I won't
complain.
