I've been following this thread, and that got me over the line. I had been experiencing very similar symptoms to the OP previously. I'm using XQuartz 2.3.3RC1 and a vanilla Wine install from Macports (running on a unibody Macbook Pro), and setting "Emulate Virtual Desktop" using winecfg has things happening for me. I've been able to play Rollercoaster Tycoon 2 perfectly, and Sid Meier's Pirates seems to be sort of working. (3d models appear as blank white areas, as do any video sequences). Both titles I had to get no-CD cracks for, because the ioctl for "CDROM verify" doesn't appear to be implemented on OS X. Sound works fine. Exciting stuff - if anyone wants me to try some stuff on OS X, shoot me a message. I'm also comfortable developing in C/C++ if it requires dinking with the Wine sources, although I don't have experience with the Wine and X11 sources per se.
