The udma/133 is setting the speed, not saying it is PATA.
From what I google, it appears that some first-generation SATA drives were modified PATA, and needed the speed set. But that all true SATA drives (e.g. any new drive) ignore that command.
In practice, 133 MB/sec is faster than gigabit ethernet, so even if it weren't ignored it wouldn't really matter anyway.
