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.

Sure it is, but only if there is sufficient hacker momentum will it
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...

Never attribute to malice what can adequately be explained by incompetence.
