personnaly I just received my shuttle SN41G2 which is has an nforce2.
I have installed Mandrake 9.1 which install almost everything well but the driver card.
So I have check for the nvidia nforce drivers and I selectionned this version : NVIDIA_nforce-1.0-0256.src.rpm.
To compile it, I had to install the kernel sources which are on the CD of Mandrake.
then log as root and type
rpm --rebuild NVIDIA_nforce-1.0-0256.src.rpm
It will compile a binary RPM located at
a small rpm -i will finish the install.
My X server was then very unstable so I installed the video driver which come has a nice installer ready for mandrake 9.1
It works very well for 2D. But I still have to investigate for opengl which is not very stable on my new station. (I have another one based on an old k7s5a with geforce 4 ti 4200 and mandrake 9.1 everything is fine)
hope it help
