It's video card dependant.  X server doesn't support resolutions not  
in VESA BIOS out of the box (at least for some video cards).  Wide  
screen resolutions are usually not listed in VESA BIOS by default.   
For Intel video cards, there's couple of programs you can try to  
change one of the VESA BIOS modes to 1440x900 (you'll need to do this  
on every boot, before X server starts).  For example 915resolution  
(available from Dag's repository) should do it for Intel 800/900
