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.
