Broadcom wireless on Arch linux

My wireless card is Broadcom Corporation BCM4311 802.11b/g. When Broadcom had not released open source drivers, I was using b43 drivers according to Archlinux wiki. These drivers worked fine till kernel version 2.6.37. From the next kernel version, it started trouble me as described in this bug. I switched to broadcom-wl and things worked fine once again. However, starting from kernel 3.0.x, each time I update my kernel, I have to recompile my drivers using

makepkg -f

and reinstall them using

pacman -U ./<package name>.xz

Now I can successfully connect to WPA networks; but not to WEP networks.
