PCMCIA GPIB help with linux-gpib-4.3.0

Hi, I'm new to the Linux-GPIB community and am hoping to get some guidance
on getting my National Instruments PCMCIA-GPIB card working with
linux-gpib-4.3.0.

TL;DR: Are there better instructions for getting PCMCIA cards to work with
linux-gpib than is what is contained in "linux-gpib-user-4.3.0/INSTALL"?

Full details:
I am running CentOS 7.7.1908, with a custom kernel
(3.10.0-1062.18.1.rt56.1044.el7.x86_64). I have successfully built the
kernel driver and installed the user space package. The instructions
contained in the linux-gpib-user-4.3.0/INSTALL file appear to be very
outdated for PCMCIA, as it makes reference to the cardmgr daemon (as far as
I know cardmgr was replaced by pccardctl and lspcmcia). I edited the
"board_type" field in "/etc/gpib.conf" to "ni_pcmcia". As instructed, I
copied the etc/pcmcia subdirectory to /etc/pcmcia. I am assuming the script
"/etc/pcmcia/linux-gpib-pcmcia" is supposed to be run somehow, when a
pcmcia card is inserted, but I am unable to get it to run from the
terminal. I am able to insert the kernel module drivers: gpib_common,
nec7210, tnt4882, but when try issuing the command:
$ sudo gpib_config 0
, I get:
failed to configure boardtype: ni_pcmcia
failed to configure board
main: Invalid argument
I checked the output of dmesg after inserting the drivers and see that the
following interfaces get registered:
[ 1495.671213] gpib: registered ni_isa interface
[ 1495.671220] gpib: registered ni_isa_accel interface
[ 1495.671223] gpib: registered ni_nat4882_isa interface
[ 1495.671225] gpib: registered ni_nat4882_isa_accel interface
[ 1495.671227] gpib: registered ni_nec_isa interface
[ 1495.671229] gpib: registered ni_nec_isa_accel interface
[ 1495.671231] gpib: registered ni_pci interface
[ 1495.671233] gpib: registered ni_pci_accel interface
ni_pcmcia is nowhere to be found. Looking in the tnt4882 driver source, I
see that all the above listed interfaces have definitions in
"tnt4882_init.c" which I assume contains all the initialization routines
when the drive module is inserted in the kernel. The pcmcia init routines
are found in "tnt4882_cs.c". It seems that PCMCIA is a dying bus interface
and am wondering if maybe the ni_pcmcia routines should have been added to
"tnt4882_init.c" some time ago or am I doing something wrong? Thanks for
the help and reading my lengthy email.
