Ok, added these in ...
options snd-cs46xx snd_index=0 snd_mmap_valid=1 snd-pcm-oss 
snd_nonblock_open=1

 

Still get a hang on sound initialisation.
Here is some info from the system...

With the no-block option set I notice that strace reports the open call 
with an "<unfinished ...>" string on the end. Looks like nothing else 
but rtcw has device open. lsmod reports it used twice, no artsd running 
so I always assumed that the game uses two connections to the module, 
especially since nothing was using the module before the game was 
started. Is that possible? You do have to switch to single-user mode 
within the game, maybe the extra connection is picked up there?

I'll keep tinkering.
