    This is surprising. I just manually verified the driver against the
    cx700 programming manual, and it seems to do the right thing. Lacking
    access to a cx700 board right now, I cannot perform an actual test.

    Where exactly is the bug about the wrong register that you mentioned?
    I'd rather fix that ASAP.

    good to know. Seems like I need to get access to a CX700 based board.

    JFYI: I wrote one but it doesn't work on the vx800/vx855, and VIA is currently
    trying to figure out why.

    I think the CPU just claims to report it but in reality doesn't... this was
    made to make some proprietary software happy, AFAIR.
