Dual head display issues with Warty

[Mike Smith]

I have a laptop with the Radeon 9000 and have it working with the following:

The only problem I have is screen0 is 1400x1050 and screen1 should be
1280x1024, but it has a "virtual" size of 1400x1050 so the entire
screen is visible by draggin the mouse to the extreme
right|left|top|bottom.
