    They cannot be enabled because they don't compile (see below).

    Indeed it fixes it perfectly.

    However this problem (undefined reference to `ide_setup_dma') was created by
    your previous patch allowing selection of PCI chipsets if IDE DMA is not set
    ;-).

    I can't apply these patches because they create more problems that they fix.

    Here is compile time hell I was talking about (result of both your patches
    applied, IDE DMA disabled and all PCI chipset drivers enabled):

    Please correct all chipset drivers and then I will apply all patches happily.
