Very mistaken. Ponting averages 50 in Sri Lanka (on genuinely raging turners in almost all of the Tests he played there) and has only played one Test away against Pakistan in Pakistan where he scored a ton so it's not fair to bring in that one. This percepton of Ponting as a rubbish player of spin is just wrong.
The problem is India and the pitches in India haven't been raging turners for ages. They've generally been slow and low with huge scores when Ponting has played on them (other than the last Test of the last series). So it's actually India and one or two of their bowlers (Harbi and Kumble) which Ponting has struggled with, not the turning conditions because there really hasn't been any.
Check 'em out; big scores abound:

As for Hayden, well in the same way you can't prove that he would have done worse in more seaming conditiosn in the 80's, I can't prove the opposite. If he has a big one in England, will you guys back off? I doubt it.
