Pascal de Bruijn has kindly generated a couple of icc profiles from my target 
shot.  The first one 
is a regular matrix designed to be used with the base curve enabled, the second 
is supposed to 
approximate Canon's standard picture style and should be used with the base 
curve disabled:

To use these, you can copy them to your home directory under 
~/.config/darktable/color/in and then 
enable them in the "input color profile" module in darktable.  They're called 
"Canon EOS 60D" and 
"Canon EOS 60D (Standard)".

Here are some sample images where I've applied the three different colour 
matrices:

HTH.
