PCIE video cards and DRI

[Gain Paolo Mureddu]

Well, you can trust the log for that, if you need to make sure, you can 
also use fglrxinfo or glxinfo to determine whether Direct Rendering is 
enabled or not. If you get someting like OpenGL Renderer String: ATI 
Radeon 9600XT or something like that, you are using DRI, if MESA shows 
up, you are using software OpenGL.

The internal and external AGPGART drivers in the fglrx module only makes 
a difference when you have hardware that is not recognized by the 
driver's GART driver. In otherwords, if you have a chipset for which the 
driver doesn't know how to operate AGPGART on. In such cases you are 
forced to use the External module which would correspond to the 
kernel-side driver.
