I think that this is because X still thinks that the second screen
exists. I guess you could try to move it over/appear on the first
screen by using wmctrl or devilspie. But the definite solution to this
problem will not come until randr 1.2 is made common and supported by
your driver. This new version of the randr extension allows, among
other things, removing and adding new screens while X is running. I'm
not so sure support for this will be added quickly to fglrx, though,
as it's already using ancient kernel and X interfaces...
