This looks like a good patch. Please make it so - who knows what other 
uses of cond_resched() we have in module init routines that might have 
deadlocks without it. The netpoll case got fixed, but please just do this.

I'd like to do my system_state movement too (the thing is, when you load 
drivers as modules you _will_ have "system_state == SYSTEM_RUNNING", so 
any initcall that depends on it being "early boot" is already broken), but 
there's no way that patch is appropriate for post-rc2. This one, however, 
looks appropriate (modulo getting some testing, of course)
