I do agree it only does something which we do manually with a lot of the
other members, however i'm not quite sure wether the compatibility thing
still holds since a number of drivers have a lot of 2.5 specific stuff
(e.g. pci-dma api changes). Regardless, here is a typical use in a
netdriver.

        /* dev and dev->priv zeroed in alloc_etherdev */
        dev = alloc_etherdev (sizeof (*tp));
        if (dev == NULL) {
                printk (KERN_ERR PFX "%s: Unable to alloc new net device\n", pdev->slot_name);
                return -ENOMEM;
        }
        SET_MODULE_OWNER(dev);
        tp = dev->priv;

        /* followed by ... */
        dev->foo = __foo;
        dev->bar = __bar;
