Maybe it would be of general interest if somebody could post
how it is _supposed_ to work? Is there a conflict between
ata_piix and piix/mpiix? A short summary could be very helpfull
to identify problems, and to reduce confusion.

I got the impression that the current implementation seems to
be very fragile wrt. the kernel configuration, the module load
sequence, and the attributes to libata.
