Pankaj: 915resolution is hack. It asks the panel what size it is. The panel says "1400x900", so 915resolutions goes and overwrite a BIOS mode to alter it to "1400x900". If you want a different mode, you need to overwrite something else. The configuration file is in:
/etc/default/915resolution
but it is only used to construct a commandline that looks like:
915resolution modenumber width height
so you can run those yourself if you need additional modes. This is fixed probably in Xorg for edgy.
