Wi-fi function broken after installing Kubuntu Jauntu and KDE 3.5

[TWO]

#System specs:
OS: Kubuntu Jaunty Jauntelope 9.04
DE: KDE 3.5.10
System: Dell Inspiron 1300
Network controller: Broadcom Corporation BCM4318 [AirForce One 54g] 802.11g Wireless LAN Controller (rev 02)

Wi-fi functionality is disabled after upgrade to Kubuntu Jaunty and KDE 3.5.10. The upgrade was from Kubuntu Hardy Heron.

Unable to activate wireless card via system settings -> network settings, or by typing the command "sudo ifconfig wlan0 up." The latter gives the following output in the terminal:

SIOCSIFFLAGS: Operation not supported

The 'dmesg' command reports that the incorrect firmware has been installed:

[ 21.242855] b43-phy0 ERROR: YOUR FIRMWARE IS TOO NEW. Please downgrade your firmware.

This bug was reported a while ago and there hasn't been any activity in
it recently. We were wondering if this is still an issue? Can you try
with the latest Karmic 9.10 release of Ubuntu? ISO CD images are
available from http://cdimage.ubuntu.com/releases/ .

If the issue remains, could you run the following command from a
Terminal (Applications->Accessories->Terminal) while running Karmic. It
will automatically gather and attach updated debug information to this
report.

apport-collect -p linux 368293

This bug is no longer an issue with the latest Kubuntu version, KDE 4 Karmic Koala. I cannot verify the case for the ongoing KDE 3.5 fork.
