I think I figured it out. It was the GCC1-?GMCH Control Register #1.
This is the register where you indicate the memory pre-allocated for  
the frame buffer for IGD (Internel Graphics Display). Plus, this is a  
16 bit register and the upper 15:7 bits are reserved. The memory space  
LinuxBIOS gets copied to must have been conflicting with this?? I will  
have to set it up so it just sets the lower 6:0 bits. Anyways, I am  
now so close I can taste it:-)
