On 12-Apr-98 Nathan Gelbard spoke unto us all:
# I've got SYSVSHM in the kernel, and MIT-SHM enabled in the
# server. Any other ideas? I recomiled the emulators for NetBSD,
# but with no effect.
# 

Just a thought.. but I would try a package that is known to use mitshm, just to
rule that out (and leave a big finger pointing at what you are trying to run). 
I know xmame in our pkg tree (emulators) uses mitshm.
