A simple more generic solution is to do this

struct things_to_keep my_bits

struct things_to_keep __persistent card_info[NUM_CARDS]

and have insmod do

load module up
open /var/run/moduledata/$modname
if exists && is from this boot then && is right size
read data into __persistent ELF section
load into kernel
init module

and rmmod
cleanup module
open /var/run/moduledata/$modname
write data from __persistent segment into file
