ubuntu 10.04 and b43-fwcutter

[Joep L. Blom]

I have a big problem with lucid.
I have an older laptop ( > 6 year old) and I have installed Lucid on it.
It's a 64-bit AMD 3000 with 512 MB.
The problem is in the wireless card. It is build woth the Broadcom B4306 
  (rev 03). On the site > 
http://wireless.kernel.org/en/users/Drivers/b43#fw-b43legacy
a description for installing in Lucid says simply download b43-fwcutter
and install, that is all there is. No deal. If you download and installs 
it nothing happens and the b43legacy module is not installed. Even 
worse. I can find the module:
/lib/modules/2.6.32-22-generic/kernel/drivers/net/wireless/b43legacy/b43legacy.ko
but a modprobe with this module tells me it cannot be found.
I'm wrestling with it for several days and now I hope somebody can write 
the magic words to solve this problem for me.
