Default xorg custom modeline validation

Dear all,

I have this machine with Geforce GTX 260M graphics card and Ubuntu 9.10 on which I am doing research. I used gtf tool to create custom modeline as given below and wanted to disable mode validation so that latest nvidia 190.42 driver would select my customized modeline.

I went through xorg specification and tried many combinations of tags and options however each time mode validation seems to be enabled and refuse my settings Xorg.0.log gives me: No valid modes for "1920x1080_70"; removing.

Below is related sections of my xorg.conf file. Could anyone please tell me how to disable modeline validation completely? What options should I use or in which order or at which section should I define them.

Thank you
