Ok, here is the response I received from Micronas when inquiring about information for the nGene PCI-Express bridge: "We have to say sorry but unfortunately we will not give access to the internal register of our chip." They gave me a data sheet for the 3975D DVB-T demodulator, but it is worthless, because it does not contain any register information either. So it appears Micronas does not WANT their hardware to be used in Linux at all. If you purchased such a board for use with Linux, I suggest you return it.
