The software opengl32 renderer is implemented using directdraw these days and that causes the issues when I experimented with wine's ddraw on windows a while ago. It is possible to work around this (if you declare the number of adapters to 1 before wined3d loads opengl32.dll) from what I remember. It is able to load the functions then but when making GL calls it crashed. Perhaps my radeon9000 drivers had a bug.
