I was able to simplify this a bit:

1. Add nomodeset to kernel command line.

2. Remove all xorg video drivers except the VESA driver.

3. Add "blacklist nouveau" to /etc/modprobe.d/blacklist-nouveau.conf.

4. Run "dracut --force" to rebuild initramfs with new blacklist entry.

This avoids the requirement for a hard-coded xorg.conf. I previously
had trouble keeping the nouveau module from loading. I had forgotten
that it is necessary to rebuild an initramfs to ensure the system does
not load blacklisted modules.
