The idea was to have the generic NI API and per-chip driver code.  I
only have the old PCIIA card with the NEC chip 7210 for which I have
not been able to find a proper datasheet anywhere.

gain the ability and retain the ability.  GPIB has been discussed about
once per year for the last 5 year and we've gotten nowhere further
for that...
