OK, here's my init file for NetBSD 6.1.5 (SET XQ TYPE=DELQA commented 
out):

.....................................
set cpu 256M
set cpu idle=netbsd
at nvr vax.nvr

set rq0 rauser=5000
at rq0 netbsd.dsk

; SET XQ TYPE=DELQA
; at xq nat:tcp=2222:10.0.2.15:22
; set console telnet=2223

boot cpu
........................................

and here's the output from the boot:
