Actually, if you look at the patch between Linux 2.6.25 and 2.6.26,
you'll see several changes like this:

-       dev->nd_net = &init_net;
+       dev_net_set(dev, &init_net);

And that's what we should be doing, I believe.

Also the kernel version probing should be fixed.  Linux 2.6.27 will need
changes to accommodate changes in Wireless Extensions API (but they are
already in updated Fedora 9 kernels).  I'll post those patches
separately.
