You have to compile the xenomai trunk for now.

Yes. I have on my TODO list, the delivery of a beta version of the ni_pcimio 
driver into the xenomai trunk. This driver will match the features range 
provided by the legacy version (www.comedi.org).

However, you should not use the comedi-rtdm-dev version, that was just a POC 
for the modified Comedi API.

The trunk version will be available soon. 

Best regards.

Alexis.
