What you see is not a mis-configuration.  Unfortunately there
is no backend for VME on Linux included in devlib2.  Only for
RTEMS or vxWorks.

I know there is at least one implementation out there using a
proprietary Linux driver for a VME bridge (not sure which one).
I've never had access to this.

So your options as I see them are to figure out how to use RTEMS,
or to find/write a Linux driver which devlib2 can be made to use*.

RTEMS is probably the easier route, although as you've found
there is a learning curve.

* The standard Linux VME userspace module doesn't support interrupts,
  and would need modification/replacement as mrfioc2 relies heavily
  on interrupts.
