Tks for hint, but today i had a brand new behaviour: before diving into
git, i tryed to add som debug printk into ssb backplane to see if there
were some difference between 2.6.35 and 2.6.36, and the magic is that
the module worked also with 2.6.36 kernel; for sure i don't really think
that my few printk made the miracle; the only difference was that i
manually made 'insmod' of ssb.ko and b43.ko, then i 'ifdown wlan0' then
'ifup wlan0' and it worked...; as it seems to me there must be some alea
somewhere, that in certain conditions makes the module to misbehave
and the AP forbids to associate to it; but i cannot get the point also
for the fact that if a restore the starting buggy situation ('insmod' is
performed by a script launched by inittat just after init), the 'race'
situation doesn't happen anymore (for now), and the wlan0 still keep
working: don't know where to hit my head......(desk already hitten!)
