Just got WWP, installed it, and got the patch. It crashes right after it displays the Titus screen. I've got a Dell Dimension 4600 running Windows XP, 1 gig o' ram, with an ati radeon 9800 pro with latest Omega Drivers, and soundblaster live card, also with latest drivers. I've got the latest version of directX and have tried running in compatability mode with no success. Any help you can give would be greatly appreciated.

Why not try the official drivers for your graphics card?
The omega drivers are usually based on the months old official versions.

Is there a simple way to get the official drivers and enable them only for that game, or be able to switch between them?

no... why would you use ancient drivers anyway? unless they contain a specific fix for a problem your encountering... theres no need to not upgrade.
