I'm not sure I understand the problem.  Can you give a more concrete
example where you get undesirable behavior?
Setting comment-start is usually needed to tell Emacs *which* of the
major mode's comment syntaxes to use (so it's only theoretically
unneeded if the syntax-table only include a single comment syntax).
