PXI platform and COmedi

Hello,

I started using the comedi/RTAI last week, for a real time control and
DAQ application; I am setting up a 2.6.16 kernel with RTAI. Currently I
use the National Instrument PXI platform, with PXI-8146RT Real time
controller and PXI 6025E DAQ card. Communication with host PC is through
ethernet.
I have seen that Comedi supports PXI-6025 hardware with ni_pcimio.o.

My question is how do you deal the PXI controller, since the installed
OS seems proprietary of National.

All suggestions are welcome.
