Wireless card, kernel module and firmware

Sometime it's not enought to have wifi card kernel modules loaded, sometime it is required to install the firmware too.
This is the case for the BCM94311MCG wlan mini-pci card which is the wifi card in the Acer Extensa 5620Z laptop.
OpenSUSE 10.3 (and OpenSUSE 11 beta 2, which is the O.S. i'm using right now) has kernel modules for that card but requires another step as root user.
Connect the PC to a network using the ethernet and run as root the following command:

/usr/sbin/install_bcm43xx_firmware

which will download and install the firmware.
Reboot the PC and configure the wireless card... everything should go in the perfect way (as happend to me with suse 10.3 and 11b2).
