The IDE drivers are machine-independent, yes.

I think I see what the problem likely is: there are four PCI IDs for
the MCP65 SATA controller, and only one of them is listed in

Try the following patch (with GENERIC):

If that doesn't work, what we'll need to know is what the PCI ID you
actually have is, which you can get via lspci or equivalent.

I don't think adjustkernel is expected to work on any currently
supported versions.
