[Wine] NWN2 Unable to Detect 3D error.

[Brackenn]

Hi. I'm running Ubuntu 8.10, My video card is Radeon x1600 with 512 of memory, and 3D graphics.
My computer is a Core 2 duo, 
Wine version 1.0
This same setup ran the game before I ripped out Windows and switched to Ubuntu. I downloaded the Linux driver from the ATI/Radeon site, and installed it. But Wine doesn't seem to know about it. I tried running the windows driver in WINE but it did nothing.
The game starts okay, but shuts down complaining about no memory and no 3d graphics.
Any Ideas?
