That is were the problem lies. It is a prebuilt kernel module (*.ko) for
2.6.10... The source is not available. That is why I need to do a mmio
trace to find out exactly what it is doing. If I had the source I would not
need the trace. I wonder if I could backwards hack MmioTrace to work with
the 2.6.10 kernel?
