seem to remember kneelers at Santa Maria Sopra Minerva in Rome, the Duomo in Florence, and San Nicolo in Bari. Any one else?

Yep. Also:

St. Peter's - Rome
Basilica San Marco - Venice
Notre Dame - Paris
Wiesskirke (Rococco era) - Austria
This other little church in Amsterdam

and St. Andreas in Montecarlo in Tuscany where I stayed for a month.

In Pisa and Lucca, I don't remember.

Large medieval churches were public halls. The reason why they have large doors was that the nobility could ride their horses inside. They didn't have pews or seats because they were intended to hold large crowds. But what does all this have to be with whether we have kneelers or not. Why make someone's grandmother change the way she has worshipped all her like just so some priest can feel good about himself. If we are simply trying to be reasonable, then we might point out that kneeling is a more natural way of praying than standing, but if standing we should learn to bow deeply rather than just depressing our chin slightly when in the presence of God.

I seem to recall learning somewhere (high school? college?) that the medieval churches were built without kneelers and the people (it's easy to overlook the obvious) knelt on the floor when kneeling was called for.
