From what I can see in the source, loadMatrix is method of class
MatrixComponent [1]:

instance MatrixComponent GLfloat_ where
   getMatrix = getFloatv
   loadMatrix = glLoadMatrixf
   loadTransposeMatrix = glLoadTransposeMatrixfARB
   multMatrix_ = glMultMatrixf
   multTransposeMatrix = glMultTransposeMatrixfARB
   rotate a (Vector3 x y z) = glRotatef a x y z
   translate (Vector3 x y z) = glTranslatef x y z
   scale = glScalef

However, for some reason it is not exported:

   MatrixOrder(..), MatrixComponent(rotate,translate,scale), Matrix(..),

Best regards
