[Buildroot] Xorg configuration for XGI chip

[Damien Borie <dbe@terawatt.fr>]

Hi.

I have to configure my Xorg X server to use a XGI Volari z9s chip. I'm 
not very familiar with this and all I tried for now only make a black 
screen.
I tried to use XGI driver from Buildroot, SIS driver from Buildroot, and 
tried to install XGIZ driver downloaded from XGI website, but it's not 
working.
I think I must insist with one of these drivers but I don't know which 
one really works.

With SIS driver, when I interrupt startx, my console re appears.
"startx" command result  with sis driver :

With XGI driver, the screen stay black forever.

The errors don't seems to be important as I don't use 3D and OpenGL.

If someone has already work on this chip XGI z9s, which driver must be 
used and how to configure it?

Thanks,
Damien.
