    It doesn't work too well, though - try it and see what happens to the
    config file after doing "make oldconfig" etc.

    The proper fix is probably something like

    unset CONFIG_PCI_BIOS CONFIG_PCI_DIRECT
    choice 'PCI access mode' \
    "BIOS CONFIG_PCI_ACCESS_BIOS \
    Direct CONFIG_PCI_ACCESS_DIRECT \
    Both CONFIG_PCI_ACCESS_BOTH" CONFIG_PCI_ACCESS_BOTH
    if [ "$CONFIG_PCI_ACCESS_BIOS" = "y" -o "$CONFIG_PCI_ACCESS_BOTH" = "y" ]
    then
    define_bool CONFIG_PCI_BIOS y
    fi
    if [ "$CONFIG_PCI_ACCESS_DIRECT" = y -o "$CONFIG_PCI_ACCESS_BOTH" = "y" ]
    then
    define_bool CONFIG_PCI_DIRECT y
    fi

    (note the "unset" and the different name spaces to make sure that we
    don't get configuration confusion).

    I have _not_ tested the above, but I tested your previous patch and it
    didn't work reliably. The above approach _should_ work, but if anybody
    really wants to see this in the next kernel, please test it out and send
    me a patch if/when it works..
