It probably comes from the times when dual-head configurations were 
still bleeding-edge, and when BIOS manufacturers assumed that if you 
had a AGP/PCIe graphics card on your bus, you wanted to use it, rather 
than the usually cheapo onboard chip.

Nowadays, NVIDIA's Hybrid-SLI [1] precisely aims to aggregate graphical 
power from the onboard chip and add-in card(s) in heterogenous 
configurations. So hopefully this trend will come to an end. At least 
on NV mobos.
