hi, i have a similar problem with my BCM4306 (Dell Latitude D600), but in my
case my wireless card is recognized and I can see the networks and at the first
time after boot i can connected me to network without problem BUT after some
minutes i loss connection and impossible to reconnect, only solution 'reboot'.
I use Kubuntu 8.10 with Kernel 2.6.27-8 (same problem even with 2.6.27-7)
the dmesg output is:

[ 1062.688255] wlan0: authentication with AP 00:0c:f6:48:52:56 timed out
and the message "assume out of range" is not true in my case because
even closer to AP i have the lost connection.
With Hardy (all kernels of hardy) my wireless card works greats, easy and
automatically and more (with the hardware assistant) but is not the case for
Ibex... It's not the same Firmware:
hardy FW version 351.126
ibex FX version 410.2160
I tested to blacklist b43 and modprobe b43legacy but my card is not recognized.
Another problem, when i test without Knetwork-manager, only with
command-line dhclient don't work, So, apparently is not a problem from
knetwork-manager...
