... yes and no -- It's happening after the corereset, which is also a 
major source of delay.  At least on non-usb targets, assuming that it 
hasn't been overridden.

Yeah, I see that, but with the patch they're still broken; only 
differently.  The ifstate_enable isn't guaranteed to succeed, so 
at netdev_register, the hardware is still in an unknown state.

From my perspective, wlan-udev.sh should do nothing if we're in 
wlan_wext_write=1 mode and the hardware is initialized.  These days the 
only real reason to do anything is if the user explicitly wants to do a 
firmware load, and that will screw with NetworkManager or other apps 
anyway.

Of course, the RightWay(tm) to solve all of these problems is to push 
the firmware loading/plugging into the kernel, so we can use the hotplug 
firmware loader and have everything up and running before we call 
register_netdevice().
