[Buildroot] Xorg configuration for XGI chip

You could check if the video BIOS allows higher resolutions for the 
framebuffer. But you probably won't get widescreen this way.

About the compiling and loading issues, I have no idea.

Newer versions of the Xorg server won't display the black-and-white 
pattern anymore, but instead a black screen. Try to run some application 
from the same console device and watch the screen, like in:

# Xorg &
# DISPLAY=:0.0 xclock &

maybe the server is up and running, but you don't think it is?

I had some fun with SiS chipsets (SiS 315) myself, so I'm avoiding it. 
Probably it isn't an option for you...

Try to post a full Xorg.0.log using the SiS driver, as it seems to be 
the best working one for now.

I do not know if the driver supports full modesetting (i.e. widescreen 
resolutions not offered by the video BIOS).

Best regards,
