Dell Inspiron 5160 Volare XP5 video setup

A Dell Inspiron 5160 with the Volare XP5 video option has 
been somewhere between difficult/impossible to configure in 
Linux and other OS's than Windows.  The default X 
configuration on this Pentium 4 box was incorrect after 
  X - configure 
(and hung the machine requiring for me a reboot when tested)

I however modified xorg.conf and appear to have a working 
configuration.

I modified the video driver from Trident to vesa
    Identifier  "Card0"
    Driver      "vesa"
    VendorName  "Trident"

I added an additional display option to Monitors 
to allow 32 bit and forced a resolution of 1024x768.
(the same one I use in Windows)

The complete text of the xorg.conf file follows.  
I do not know where to report this so that the documentation
can contain this workaround or possibly the autoconfiguration
code could be changed. I probably have to figure out dmesg
before this information is completely usable.
