Are these old versions of nm and wicd only supporting the deprecated
WEXT interface? If this is the case you have to set
CONFIG_CFG80211_WEXT=y in your config.

You also need a firmware for this device /lib/firmware/brcm/bcm43xx-0.fw
and /lib/firmware/brcm/bcm43xx_hdr-0.fw are needed.

When the device gets detected by brcmsmac, it is probably not a problem
in the Broadcom driver.

When you want to use the property closed source Broadcom driver then you
have to blacklist the in kernel drivers. When you want to use the in
kernel drivers, BCM4313 should get detected and the modules should get
loaded like it is done for every other PCIe device.
