Ok, your IDE interface is supported by pata_ali...

Right, as it looks above, pata_ali should be able to support your IDE
interface, so you might not be needing the pata_acpi thing after all.
So yes, blacklisting it and verifying that your system still operates
normally would be something to do. If it does, you could also build a
kernel with pata_acpi disabled (that is, provided you build your own
kernels).
HTH.
