Only DRI will use AGP transfers, so if DRI is disabled is does not matter what AGPMode you are setting. DRI is used for 2 things, 3D hardware acceleration (mesa libraries) and EXA 2D acceleration (in driver). Without DRI, 3D graphics will be software rendered, and EXA will be terribly slow. In Karmic, the driver will switch to XAA if there is no DRI.

I would be curious to see if the memory allocation is different in Karmic. Do you have two monitors connected, and a virtual desktop spanning both?
