As Tom pointed out earlier,

    kernel: audit(1177078045.770:10): avc:  denied  { name_bind }
    for  pid=6497 comm="httpd" src=1185 scontext=root:system_r:httpd_t
    tcontext=system_u:object_r:port_t tclass=tcp_socket

shows that SELinux is blocking apache from using any port except 80
(and perhaps 443 for SSL).

Running audit2allow against that line shows the selinux rule

    allow httpd_t port_t:tcp_socket name_bind;

would allow apache to bind to any port. That may be more open than
you want to make it, though.

I haven't messed around with selinux much, I've basically just read
the O'Reilly book on SELinux. I believe you need to install the
selinjux-sources package in order to customize the rules. There's
probably a decent FAQ or HOWTO document out there, though.
