in your /etc/X11/XF86Config(XF86Config-4 depending on which version of X your running) you should see a section like this ...
Section "Screen"
Identifier "Screen0"
Device "Card0"
Monitor "Monitor0"
DefaultDepth 24
SubSection "Display"
Depth 1
EndSubSection
SubSection "Display"
Depth 4
EndSubSection
SubSection "Display"
Depth 8
EndSubSection
SubSection "Display"
Depth 15
EndSubSection
SubSection "Display"
Depth 16
EndSubSection
SubSection "Display"
Depth 24
Modes "1024x768"
EndSubSection
EndSection
Just change the default depth to 16 and make sure there is a subsection for 16bpp and that it has the correct modes you want to use. That should be all you have to do.
