You probably don't have r11 pointing to the data structures it expects.
I expect there is another entry point somewhere which is more
appropriate for call-from-kernel use.  (Also, another reason to think
it's not designed for non-ROM use is that it uses jsb/rsb calling, not
call[sg]/ret.)

Another VAX, dunno.  But...

...there is.  I found one and was using it as documentation of a sort
when picking apart the code that pokes at the 2681.  See pc532/dev/scn*
(at least in the 4.0.1 source tree).  pc532/stand/common/scn.c might be
useful too.
