Smoke: The well known Miika Hämäläinen (aka MiikaH) patch (http://blenderartists.org/forum/showthread.php?t=158317&page=42)
* Better (and windows enabled) OpenMP handling (> 2x-5x speed)
* More Volumetric Texture mapping options (heat, etc) <-- Matt if that's not to your liking, just revert that part, it's separate anyway
* Initial velocity taken from particle settings (no more slow starting)
* Option to select compression method (there seem to be a bug in my high compression usage, at least it's been reported to result in exploding smoke - better use low compression for the time being)
It's been tested since a while but as usual please report any (new!) bugs. ;-)
