Additional Comments

Installed and ran fine w/steam, no tricks required. Performance did increase when multicore setting was disabled. I am using the default ATI drivers that come w/Ubuntu and I have a Radeon HD4770 + AMD Phenom x2 550, the frame rate was quite sluggish. I think its due to the drivers rather than the card since I had all my graphics settings on low and resolution downscaled. Multiplayer froze twice on me, once during loading, and another at the end of the match. Not sure if it was truely frozen or just taking a really really long time to load.

- To get past the "Incomplete Installation" error:

Use Wine-1.1.35 or later

- To get past crashing at the MOTD display when joining a multiplayer game:

Either: Use native urlmon.dll (can be limited to just left4dead2.exe),
Or: Use wine-1.1.27 or earlier.

- To improve the performance

1. Enable multicore rendering.  This increases performance by 10-15 fps in most places for me.
2. Use the following patch:
http://bugs.winehq.org/attachment.cgi?id=24812
   This increases performance by 50-60 fps in most places for me.  Note that you may need to minimise/restore or otherwise lose and regain focus of the game to fix the flashlight and some textures if using this patch.
   The performance is so much better in wine-1.1.33 that this doesn't seem to be needed any more.  The framerate with this in wine-1.1.32 was still higher than the framerate without this in wine-1.1.33 though.

- To get past the crashing/restarting/broken game files which occurs every few minutes during gameplay

Add -lv to the launch options in Steam.  This enables low gore mode, which for some reason fixes the problem.  Low gore mode doesn't look as great, but it's worth it for the stability.
