    This looks to me like a memory-mapped I/O region. The ISDN driver
    does this too, but they _know_ this is "wrong" and comment it.
    The problem being no support for requesting regions of the address
    space. This isn't a huge problem in this case, since the address
    is above the legal ix86 I/O region.
