CXO 3.0.1 using the February release of Wine runs LW fine (dongle issues aside), for the most part, but CXO 4.0 (based on July/August Wine) results in a very badly broken interface that render the application unusable.
For now, you will need to side-install 3.0.1 with 4.0 to allow LW to be run, or use October 2004 Wine to get a usable Discovery-mode LW on linux.
