Here's what I use with a 4650, comments removed to save space.
Notes:
1. Don't use AEI: http://www.wonkity.com/~wblock/docs/html/aei.html
2. Monitors are assigned to connectors in the Device section.  The
    Position option in the Monitor section defines what part they show.
3. This is one desktop across two monitors, the combined size set in the
    Virtual line.
4. HAL is not installed, but I'm fairly sure this will work either way.
