It would be a miracle.  There hasn't been much support for additional NI 
devices for about 15 years apart from simple changes to support PCIe, 
PXI and PXIe variants of existing PCI cards.

Perhaps you could get the NI DAQmx drivers working, but Debian is not 
officially supported, and the library API will be rather different to 
comedi.
