Call me crazy, but I would figure if they say "socket A and 370 compatable" then it is probably compatable. I might be missing the real question here so pardon the smartassedness
Any s370 will fit on s-A. Not necessarily true the other way though- later s462 HSF's used all three sets of clips, rather than just the center one. This may or may not cause interference on P-3 boards. It probably won't in 99.9% of cases, but I don't want to make this an absolute rule and be caught on that last little fraction of a percent.
