Build in the agpgart module and see what it says.

My box says

agpgart: Found an AGP 2.0 compliant device at 0000:00:00.0.

and then when the video card boots

agpgart: Putting AGP V2 device at 0000:00:00.0 into 4x mode
agpgart: Putting AGP V2 device at 0000:01:00.0 into 4x mode

(but I could tell anyway, because 2.0 -> 1x, 2x, 4x, not 8x).
