I run Linux on an OB4000, so here are some changes you will probably
want to use.  The following are some selections from my
/etc/X11/XF86Config.  I use the setup below for the LCD and for an old
VGA monitor, but I also show another configuration for a SVGA monitor,
so you have some idea what clocks are available.  You will want to use
the svga display driver, since it is optimized for the wd chipset.

I am not showing all of it, but I think these are the changes you will
need.  You should be able to manually edit your file and either
uncomment some sections or add in parts of what I show below.  Let me
know if you need more information.
