thanks for your efforts :) I tried out the wl driver on ArchLinux but it didn't
work either. However, on Debian the wl driver works with my card:
$ uname -a
Linux noname 3.2.0-4-amd64 #1 SMP Debian 3.2.63-2+deb7u1 x86_64 GNU/Linux
[ 97.463846] wl 0000:02:00.0: setting latency timer to 64
[ 97.492386] INFO @wl_cfg80211_attach : Registered CFG80211 phy
[ 97.493105] wlan0: Broadcom BCM4359 802.11 Hybrid Wireless Controller
On ArchLinux I noticed that there is always (for b43 and wl) the same error
(INVALID_DEVICE_REQUEST) in the dmesg output after the broadcom stuff:
[ 587.974839] wl0: online cpus 1
[ 587.975382] wlan0: Broadcom BCM4359 802.11 Hybrid Wireless Controller
[ 587.983443] wl 0000:02:00.0 wlo1: renamed from wlan0
[ 588.134778] AMD-Vi: Event logged [INVALID_DEVICE_REQUEST device=00:00.1
I found only one entry on google  with the same error and interestingly
enough that user has the same wifi card and laptop model (HP Elitebook 755 G2
with AMD processor). Unfortunately the given solution (add *intremap=off* as
kernel parameter) does not work for me :(
Howsoever: It's not a b43 problem. I don't know...
