b43 module doesn't work after suspend

[Antonio Messina]

Hi all,

After suspend to ram my wifi doesn't work. Unloading the `b43' module 
and re-loading after resume "fix" the issue, but it would be better if 
it will deal with the suspend/resume cycle smoothly.

My card (MacBookpro8,1):
03:00.0 Network controller: Broadcom Corporation BCM4331 802.11a/b/g/n 
(rev 02)

Kernel: 3.2.1 vanilla x86_64
Distro: Debian testing
b43 firmware: 666.2 (2011-02-23 01:15:07)
