The kqueue(2) manpage does refer to the manpage for the poll(2) system call,
which is an older alternative to using kqueue. The same goes for select(2), 
which is also an alternative to using kqueue(2) or poll(2).

None of these have any relation to polling of the network interfaces as
described in the polling(4) manpage.  
The only connection between poll(2) and polling(4) is that they have similar
names.


So, to answer your question: No, you do not need to have polling enabled in
order to use kqueue.
