Play-off chasing Bolton had looked set to spoil the party when Chris Eagles gave them a 19th minute lead but an improved second-half effort from the champions was rewarded when Noone curled a free-kick in the 68th minute.
While Cardiff are assured of Barclays Premier League football, Bolton are among those still dreaming of promotion, and despite failing to claim all three points Dougie Freedman's side remain in the top six ahead of the final round of fixtures.
There was an exultant atmosphere among the home faithful as they turned out to celebrate the title success of Malky Mackay's side.
Bolton graciously gave their hosts a guard of honour as the teams came out, but their respect almost extended to giving the Welsh club the lead after just 34 seconds.
Craig Conway was afford acres of room down the right and when his ball eventually broke to Jordan Mutch just six yards out he looked certain to score, but Adam Bogdan made an outstanding save low to his right.
It was the visitors who grabbed the opening goal against the run of play when Sam Ricketts skipped past Conway down the Bolton right and his pull-back was emphatically driven home by Eagles.
Mackay decided to introduce Tommy Smith and Noone off the bench after the break, and the former should have had Cardiff level in the 65th minute.
Noone rolled a well-weighted pass across the face of goal to find Smith unmarked just six yards from goal, only for Bogdan to scramble heroically and make the save.
But the Hungarian was finally beaten just three minutes later, Noone stepping up to curl a free-kick inside his near post.
