Versions 07 through 12 - versions which used the Presto rendering engine.
Everything I tested
What does not
Sound in Flash videos (but Flash is a separate plugin, thus I do not hold it against Opera in this test.)
What was not tested
Voice commands and mouse gestures
The Opera browser runs very well and in some cases seemingly better than its native Linux counterpart. The voice-command feature installed flawlessly, but I was not able to test it due to a microphone problem that I have yet to resolve (not Wine-related). The Flash installer executable worked as well and installed Flash, but I was unable to get sound on Flash videos such as the ones Youtube. But since Flash is a separate, independent, unnecessary plugin I will not hold it against Opera.
