A timely new Battlefield 2 Community Update (thanks Frans) has details on creating a BF2 account and the game's Battlerecorder function, as well as a demo note:

ATI Cards and Battlefield 2 Demo
In testing the demo, EA has encountered some visual issues on certain ATI cards with the previous Catalyst drivers (5.5) and are working with yesterday's 5.6 release to discover if the issue is resolved. If in playing the Battlefield 2 demo you encounter texture corruption of any kind, we recommend rolling back to the Catalyst 5.1 drivers. ATI is aware of this issue and is working to resolve it.
