Hmm, I use SMP motherboard Intel STL2 with ServerWorks ServerSet III LE
and integrated ROSB4:
http://support.intel.com/support/motherboards/server/STL2/
I can't found any notes here about the controller.

Could you please point me to any kind of "official" announcement
from Intel, chipset or controller producer?

It DID work with my IBM drive (IC35L040AVER, noted in ata(4) man page)
before PAE intergration without problems. Now I turned it off - 
it panices 4.9-STABLE under heavy load.
