I am not pretending to use this, but as a general curiosity, when the AT32UC3C2512C datasheet says in page 1259, Table 40-20, parameter Iout, that the internal 3.3V regulator has a 35mA DC output current, does it mean I can actually use it as a power source, as long as I don't use more then 35mA out of it?

I think pg. 88 and the info/diagrams on pages 46 onward answer your question quite well:
So essentially it's not meant for use supplying external components, rather so you can add decoupling if it is being used. To add a pin for decoupling like this is very common (since large value caps are not feasible on the die)
