No, I'm afraid not. Libsas has been released for nearly seven years and no-one has noticed in all that time, which means it's a really rare thing to do. Everyone who uses SAS controllers usually has either a direct connection or an expander. There's no real reason to buy expensive kit and then plug it into a cheap port switch. That said, it's possible that some of the firmware SAT blob based controllers, like the MPT ones might have PMP support ... but because of the rarity it's likely to be buggy.
