Yes, of course we have a bug. I think that we have plenty of them in 
fact. ;-)
I would like to share the code but it is a little early since we are 
trying to figure out what we have to do.
Something is written started from what we have found in the sources but 
we still have to learn.
The RTDM API documentation is good but we have very little knowledge on 
how RTDM drivers should be used with Xenomai.
We lack general information.
Since the following links are broken now :
http://www.xenomai.org/index.php/Weblinks#Installation_of_Xenomai_and_RTDM_Driver_Writing
I remember that there use to be here a documentation about the RTDM 
driver for CIF boards, it was years ago.
My colleague is actually working on the driver, I intervene here because 
I like writing in English and I am the support guy. ;-)
