If you customize your system so that it does not use the method provided
by the package, then it is your responsibility that you replace that
method with something that will do an equivalent job. I cannot be
responsible for what happens when you override my scripts.

Shutting down the pcmcia services involves two distinct and separate steps:
(1) turning off and "ejecting" the cards; and
(2) stopping the cardmgr daemon.
These two steps must be completely independent to allow for the first step
to be performed without performing the second. (Otherwise, "hot-swapping"
of cards is not possible.) Unmounting network filesystems is part of step
1. Performing this task during step 2 is unnecessarily redundant, since
step 2 is never performed unless step 1 has been completed. Since the
/etc/init.d/pcmcia script is part of step 2, the NFS umount code should
not be moved there.

You should set up your system to umount the NFS filesystems when the card
is shut down (during the "eject" stage). You can borrow the code in the
/etc/pcmcia/network script if you want (and actually, I recommend that you
do), but you should modify your scripts to do this important task.

I have nothing to do with the netenv package. If you want to work on this
or offer suggestions, I suggest that you contact the netenv author. I'm
sure he would welcome any prototype code or suggestions that you are
willing to give him.
