"Failed to initialize DMA" only 2G ram, 8400 GS G98 313.30

Fedora 18, even tried vanilla kernel. Never got nouveau to work, just hangs.
I know of Arima SW310 mb:s using other graphics cards that is working well. Never got this graphics card to work.

Be patient while I figure out how to upload the bug report.

I found a Fedora-provided binary nv_drv.so 2.1.20 that kind of started but was very slow and gave me this:

(WW) NV(0): Failed to reserve EXA memory for the screen or EXA returned an area with a nonzero offset.  Don't be surprised if your screen is corrupt.

Is my card broken?
