NVidia 6600 AGP - Can I set 1440x900 resolution in some way?

Recommended by Wim's BIOS...

I have AGP card NVidia 6600, but 2 capacitors blowed up and now I am waiting for their exchange.
I now that there's no support for resolution bigger than 1440x900, but I can't set 1440x900 resolution, maximum wide screen resolution is 1280x720.
Can I set 1440x900 resolution in some way?
