From Graeme Dice's post #258109 of 14 March 2004:

All magical quickness effects, such as that from the boots of quickness, the jade armor, the quickness spell, and the champion's trident give you an extra action per round, but do not stack with each other. Heroic quickness does stack with these items, as I have a 125% heroic quickness unit with a jade armor that gets 5 attacks the first round, and 4 attacks the second round.

EDIT: furthermore, the stacking is multiplicative, not additive. As GD's post states, his HQ of 125% (2.25x) plus the armor's 100% (2x) = 4.5x (5 on 1st, 4 on 2nd pattern), and not the 225% (3.25x) of a simple additive stack. IMO, this makes the HQ HoF ability hands-down the most valuable award you can get on a leader.
