I'm trying to think where you 2D card is. Please tell me if i am wrong but Voodoo II's were 3D only. Therefore X should be configured with the 2D card (if supported) and then the glide/glut/opengl etc... packages should be installed for 3dfx support. You may also need the 3dfx kernel module to go with /dev/3dfx. Mouse not working, could be gpm or "AutoDectect" is in the mouse config section, change it some mice don't like it.
