Well, the Austrians certianly did have a long combat experience of using mass, particularly if "mass" is two or more regiments! So did the Prussians. Rossbach and Leuthen spring to mind as immediate examples from the preceding Seven Years War :o)
Superficial evidence certainly seems to suggest the Austrians organized and used cavalry in mass at Austerlitz and Wagram, and the Russians at Austterlitz. Frankly, I am not sufficiently familiar with the details of Russian, Austrian, and Prussian actions in the Revolutionary or Napoleonic period to come up with other examples, but use of mass certainly seems to have been within their grasps -- as a separate aspect form the quality of the usage.
What is it that you would identify as distinguishing the manner of usage between the French and the Coalition armies?
