You're manually setting the VertRefresh and HorizSync value for your 
monitor and you're also defining a custom modeline. This shouldn't be 
needed and is possibly why you're getting a blanck screen.
In your xorg conf, remove the Modes section and rewrite the Monitor 
section like that :

Section "Monitor"
   Identifier   "Monitor[0]"
   ModelName    "ACER AL1916W"
   Option       "DPMS"
   VendorName   "ACR"
EndSection

The lspci output doesn't give me any new information. I still don't know 
how to reference this board in the driver, I need a brand and model. 
 From the pci id, the brand is PcChips, but I don't have any crystal 
ball around to guess the model. It should be pretty obvious if you look 
at the motherboard itself, the model is most likely written on the board 
itself.
