"$" is only a special character in regexps in the search string
(not the replace string).  Hence, you want to do something like
(replace-regexp "a$" "a\nb\nc\n").  If doing this interactively,
"\n" is also interpreted literally.  So you have to insert an
literal newline, using C-q C-j, e.g. the interactive key
sequence would be:

M-x replace-regexp RET a $ RET a C-q C-j b C-q C-j c C-q C-j RET

hope the clears that up a bit.
