For me in order to increase the resolution , during reconfiguration of the xfree86 while selecting monitor , i choosed easy install , i selected the 17'' and finished the installation.
After that i could increase the resolution in gnome till 1400x1050 which is adequate for me at the moment. I haven' t manage to make higher resolution , but i think it has to do with upplying specific monitor specifications such as vertical and horizontal sync. This is done if selecting expert installtion and giving the information , but i can't find mine yet.
I just figured out how to increase the resolution to 1680x1050 @ 85 Hz on my D800.
Edit /etc/X11/XF86Config-4 and scroll down to the "Monitor" section and change the values to
Section "Monitor"
Identifier "Generic Monitor"
HorizSync 30-107
VertRefresh 50-185
Option "DPMS"
Modeline "1280x800" 159.74 1280 1296 1552 1664 800 800 815 835
ModeLine "1680x1050" 214.51 1680 1800 1984 2288 1050 1051 1054 1103
EndSection
Enjoy!
