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.

Thanks
Greg
