Xorg.0.log for kernel option nomodeset but without xorg.conf

For the latest Koji packages, X does not abort anymore when "nomodeset" is added to the kernel options. Instead, the monitor powers off. There is no response to keyboard input and the system has to be powered off. Installed packages include:

- kernel-
- libdrm-2.4.6-6.fc11.x86_64
- mesa-*-7.5-0.13.fc11.x86_64
- xorg-x11-drv-ati-6.12.2-12.fc11.x86_64
- xorg-x11-server-Xorg-1.6.1-11.fc11.x86_64
