I don't do bash, but it apparently does parameter substitution
similarly to ksh. Looking at /etc/rc2, I see it executes the scripts
in /etc/rc2.d by doing "/bin/sh <script>", so that first line
specifying the shell is ignored. The parameter substitution your
script is using is not supported in sh, so you'll have to change it.
E.g., you could do something like the following instead (not tested):

su `expr $display : '.*:\(.*\)'` \
-c "/usr/local/bin/vncserver :`expr $display : '\([^:]*\)`"
