All, please correct me if I am getting this wrong.
Gavin,
Are you getting the speed from the NetworkManager applet, because that
only reports on the initial connection speed of the interface. To get a
current rate you must use iwconfig or another application that gets the
rate dynamically.
The code for the b43 driver starts the interface at a low rate and
constantly monitors the signal quality and adjusts the transmission power
and rate depending on the quality. In a good environment the connection
should remain reliable and the driver will steadily increase the
transmission rate.  The less reliable the connection the lower the rate. 
I consistently get 12-24 Mb/s with the driver on a stock Fedora 7/8 kernel
on a 4318.
I have had connection quality problems before, related to the channel I
was using and interference  from various other AP's in the neighbourhood.
So you might want to check this.
Thanks
Simon.
