I believe this will be FAQ soon. Recent Intel chipsets do not have IDE interface anymore. Other vendors picked up but are not well supported by current drivers. Fortunately there is a generic ide driver. Although it is enabled in the distribution kernel it does not attempt to enable the controllers. It appears to me adding this command-line option is safe. Please note the following line in dmesg output. IDE generic will claim all unknown PCI IDE storage controllers. MSI P35 Neo2, ICH9R, Marvel 88SE6111 PATA/IDE chipset

I don't think this is needed nor desired. @kernel: Do you have any input?
No reply and I still think this shouldn't be done.
