Ok, what is a NI driver?

oops ...

the jr3_pci. It's a pci card, with a dsp to read the signal from a force 
sensor.

It's a lot of work ..... but there's one think that I don't understand. Are 
you modifying the comedi sources? Because is yes, the idea is to have not a 
fork of comedi, than the efforts in the comedi team then will be used by the 
xenomai team.

thank for the mail and the clarification.

I have no idea about the comedi drivers structure, neither the xenomai. I can 
be a tester, sure. I have just compiled, making a debian package, installed 
and sent the test. If I can have this driver, I can use xenomai if not, I 
have to return to rtai .... and I think that it's very interesting in my case 
use xenomai and not rtai.
