Okay, now is loaded.

Uhg, you're experiencing some kernel errors coming from pm_hibernate 
:-?. Okay, this can be normal because power management capabilities are 
still unsuspported for your wireless chipset.

Another thing I don't like from above dmesg:

***
[22474.302524] b43-phy0: Broadcom 4331 WLAN found (core revision 29)
[22474.302549] bcma: Switched to core: 0x812
[22474.302973] b43-phy0 ERROR: FOUND UNSUPPORTED PHY (Analog 9, Type 7, Revision 1)
[22474.302978] b43: probe of bcma0:0 failed with error -95
[22474.302988] Broadcom 43xx driver loaded [ Features: PMNLS ]
***

Looks like having some sort of problem... checkout this thread:

Trouble with Macbook Pro 8,2 (broadcom 4331) and latest b43
http://article.gmane.org/gmane.linux.kernel.wireless.general/81667

Besides, consider reporting your findings/problems at linuxwireless 
mailing list :-)

Hum... upstream docs tell nothing about that package.
