If we use that parameter on older kernels, is it just ignored? I'm hoping I can just make that a default for my live CDs, etc.. Also, how is that handled in libata? (ie. we typically want to force exposing the HPA regardless of driver selection.) Alan, given your emphatic ack, is libata likely to follow the same model. Any chance we could have a single boot param that handled both drivers? I mean instead of having 2 module params.
