got a similar problem with my Voodoo 3000 AGP, when I try to run XF86, I've got nothing at all (the screen goes blank) neither I can switch to another tty. :( I've tried everything, thus include dpkg reconfigure xsever-xfree86, editing XFreeConfig-4, BusId is correct 1:0:8 AFAIK, XF86Config, starting tdfx module via modprobe/insmod... arghhhh I give up. :P
