A thing that's leaping out to me here you probably already have.
There's a hotplug rc script(s) that throws every kernel module in the
pack at the kernel like mud at a wall, and hope some of them
stick. It's for 'coldbooting' hotpluggable devices. Don't ask me
where it's hidden. There's Cold War between hotplug and this
particular box. Is it /etc/hotplug/*.rc?

That and a simple lsmod |grep <module> gets your card type. 
next, a trio of these:

if <wifi> then set up wifi and nuke the other nics
if <nic1> then set up nic1 && nuke etc.

That's the bones of a simple script to allow you to set up
according to which network you are on. You can, I am sure, ping
certain numbers or check for a hostname at this IP to
differentiate between networks. You can cobble up a bash script?

You could have this script run by a post-install command in
modules.conf on each network module and it would all go
automagically. Why bother reading up on a package to see if it
will configure to your tune? That sounds like work.
