Nah. I use it on this laptop (Intrepid w/Dynex PCMCIA wireless card):

$ dmesg |grep Broadcom
[   38.556072] b43-phy0: Broadcom 4318 WLAN found
[   38.751214] Broadcom 43xx driver loaded [ Features: PLR, Firmware-ID:
FW13 ]

and it works without issue (I'm using it now).

$ iwconfig

irda0     no wireless extensions.

wmaster0  no wireless extensions.

Note: I use a different fixed IP for wired and another one for wireless.

And when using the wired (which I've just used wicd to switch to for the
output):

$ ifconfig

And now I'm back on wireless via wicd (point & click - no reinit of
networking etc).
