For some strange reason, I can not get the pdf...  

Anyway, the original patch had "ich_pata_100".

And "Gaston, Jason D" <jason.d.gaston@intel.com> didn't complain about it.
it's a "bit" confusing with all "native" AHCI SATA chipset that have to emulate

So, whom can we trust? I've seen wrong specs, but you know "To err is human".
