I tried netconsole, and it somehow works, but when suspending it says in
an "infinite" loop:

unregister_netdevice: waiting for eth2 to become free. Usage count = 1

And then it never goes to sleep. 
BTW: same if I use radeonfb as a module and try to blacklist this
module. It complains that radeonfb is still in use. 
Arghhh :)
