Note by selecting this, you must made your driver slower.  Did you read
the help for the option?

By selecting this you made your driver bigger, probably for no reason..

After staring hard at my source, I ran another diff and found that
net_init is not listed in export-objs.  Oh well, it's better to compile

Attached is a patch which fixes things.
