There's no perfect mapping, but I've been pretty happy with Exults
conversion (From Exult's audio/xmidi.cc file (exult.sourceforge.net)):

// This is a default set of patches to convert from MT32 to GM
// The index is the MT32 Patch nubmer and the value is the GM Patch
// This is only suitable for music that doesn'tdo timbre changes
// XMIDIs that contain Timbre changes will not convert properly
