If the driver complains about unknown mode 1440x900, execute

gtf 1440 900 60

(the syntax is gtf horizontal vertical refresh_rate)
that will give you a modeline as output

for example for 1280 1024 85 (my external monitor) the modeline is
1280x1024_85.00 159.36  1280 1376 1512 1744  1024 1025 1028 1075  -HSync +Vsync

Note the first 1280x1024_85.00 is the name of the mode, the rest are
some parameters the video driver needs to handle the mode correctly.

Then execute the following:
xrandr --newmode <modeline>
xrandr --addmode LVDS 1440x900_60.00
xrandr --output LVDS --mode 1440x900_60.00

Replace numbers if necessary. This works for me. My system-config also
doesn't display the right modes for my monitors. I'm not sure about
automating it (someone else will surely chime in); I execute something
similar in a script manually after I log in to get my dual head
display to my liking.
