Apple's OpenGL implementation is fine. It's the crappy Intel drivers that won't allow you to get this working. There's a bug in the Intel GMA 950/3100 drivers that will cause glCompressedTexSubImage2D{,ARB} to fail and crash in the driver. There's no workaround in standard Wine for this, and no fix on the radar from Apple.

CodeWeavers has workarounds in their CrossOver Games product (check their source, surface_upload_data function in wine/dlls/wined3d/surface.c) that allow the Intel cards to function somewhat better with Direct3D. But without buying CrossOver Games or compiling from source, you may be out of luck.

That said, I added the --cxgames option to my build script a couple of days ago. Still a bit fresh and not entirely supported but it may be worth a shot. -r
