I don't know why, but - on an old machine too - I had to correct
HorizSync and VertRefresh manually. The XFree documentation says that a
resolution does not work if it would exceed VertRefresh.

I asked the vendor homepage and the owner of the monitor and altered the
numbers :

Section "Monitor"
        Identifier      "My Monitor"
        VendorName      "Unknown"
        ModelName       "Unknown"

        HorizSync 31.47-79.98
        VertRefresh 50-75

now works.
