    It depends on what sort of device you are writing a driver for. If
    the driver is for a PCI card, there are generic functions to locate
    all devices in a list of PCI IDs, and other useful things. The driver
    will also have to interface against one of the subsystems of the
    kernel, like SCSI or Ethernet. These interfaces occasionally change,
    of course. If you have unresolved symbols, I'd suggest locating those
    symbols in the header files from the last working kernel version, and
    then look in the same header files from the new kernel for similar
    functions.
