Debian's kernel is patched such that ata_piix only handles SATA controllers,
and the old piix driver takes over for PATA controllers:
http://svn.debian.org/viewsvn/kernel/dists/trunk/linux-2.6/debian/patches/debian/drivers-ata-ata_piix-postpone-pata.patch?revision=13847&view=markup
I guess this was done while libata was still under heavy development,
and the old driver was considered more stable then.
If you are curious, ask the Debian Kernel Maintainers.
