Xorg.conf G3 450 B&W

This is an xorg.conf file for a G3/450 B&W with PCI ATI Rage and a Studio Display 17. The xorg with tty's switching will only work if linux-firmware-(non)free is installed, otherwise it will crash after terminal switching or just hangs on a half broken screen. I can also confirm that it works on debian Squeeze 6.02. So Debian 5 Lenny, Debian 6 Squeeze and ubuntu 11.04 work fine. Although ubuntu and probably debian testing with newer kernel need the "video=offb:off" option in yaboot.conf to disable a conflicting framebuffer, and uncomment the aty128fb in blacklist. I can also confirm that 1900x1200 is no problem on the pci G3 with debian lenny, probably newer versions and the agp G4 will also work since they use the same xorg.conf and driver. Just add the resolution to my xorg.conf.txt posted earlier and startx
