I don't see any option in gdm to change the refresh rate. I guess Gnome
uses something like xrandr to change the rate during its startup, but
that is still after gdm is done. The only solution I see right now would
be to revert to your old sync ranges in xorg.conf and try to force 57Hz
by reducing the range width.
The other solution would be to request the addition of a refresh rate
option in GDM, that means reassigning this bug to gdm as a wishlist. But
I don't think it will be accepted soon...
