Try removing declare(M,nonscalar); then
(%i1) map('conjugate, [M,M[1,1], M[%i,42]]);
(%o1) [M,M[1,1],M[%i,42]]
I'm don't know everything that declare(M,nonscalar) does, but declaring something
to be nonscalar mostly changes the way an expression involving noncommutative
multiplication simplifies. The conjugate code has various checks for nonscalar
atoms--maybe these checks are silly (I can say that because I wrote the conjugate
code :)
