Pretty much everything. I was able to install and play the game all the way to the end.
What does not
Cut scenes (i.e. "cinematics") have a very noticeable timelag on my machine which makes them very annoying to watch. The in-game stuff works great though. Game hangs approximately every 2 hours and needs to be killed manually. Starting the game again from the last checkpoint does work.
What was not tested
AMD Athlon(tm) 64 X2 Dual Core Processor 4400+ (2 GHz) 3 GB of RAM NVIDIA GeForce 8400 GS 512 MB (using 304.116 drivers)

If you have any issues with crashes on mouse/keyboard input, corrupted graphics or other issues: try disabling the Steam game overlay.
Even if it it doesn't break the game per-se, it might crash when you attempt to open it. Disabling it preemptively might be a good idea.
For some users, it seems necessary to override the DirectX 9 libraries used by the game. It doesn't seem to be needed in all setups, specifically not for Wine 1.7.13+ users with NVIDIA proprietary drivers, but if you see a blank screen or graphics corruption, try overriding the following libraries, either manually or through Winetricks:
