In bx:
/ircuser <something>
After that you need to reconect. If you see the same 1001 (which is your user's UID) try turning off the identd, run by inetd (find the proper line containing 'identd' in /etc/inetd.conf and comment it, after that kill -1 <pid of inetd>) or standalone (kill <pid of identd process>)
