Currently, you have to set a registry key to enable the Mac driver:
[HKEY_CURRENT_USER\Software\Wine\Drivers] "Graphics"="mac,x11"
An issue I ran into with the registry approach is that it causes Wine to use X11 to show the 'Updating the Wine configuration' dialog during the WINEPREFIX creation. It's pretty misleading and could easily give the wrong impression!
Wine does shift to using the Mac driver once regedit has had a chance to be run.
