okay, to follow-on from my last post. I managed to get things working as
follows:

I downloaded the latest 8.10 alpha 6, deleted the old partitions and
performed a CLEAN INSTALL.

by default there is NO FIRMWARE installed.

I had to manually follow the instructions on: 
http://linuxwireless.org/en/users/Drivers/b43#devicefirmware
(b43-cutter utility NOT installed by default)

----------------------------------------------------------------------

Use version 011 of b43-fwcutter. 
Download, extract the b43-fwcutter tarball and build it: 

wget http://bu3sch.de/b43/fwcutter/b43-fwcutter-011.tar.bz2
tar xjf b43-fwcutter-011.tar.bz2
cd b43-fwcutter-011
make
cd ..

Use version 4.80.53.0 of Broadcom's proprietary driver. 
Download and extract the firmware from this driver tarball: 

export FIRMWARE_INSTALL_DIR="/lib/firmware"
wget http://downloads.openwrt.org/sources/broadcom-wl-4.80.53.0.tar.bz2
tar xjf broadcom-wl-4.80.53.0.tar.bz2
cd broadcom-wl-4.80.53.0/kmod
sudo ../../b43-fwcutter-011/b43-fwcutter -w "$FIRMWARE_INSTALL_DIR" wl_apsta.o

----------------------------------------------------------------------

then I did "modprobe -r b43; modprobe b43" then got prompted for key..
but STILL TIMED OUT.

then I followed the excellent instructions from Larry Finger here:
https://bugs.launchpad.net/ubuntu/+source/linux/+bug/182716

I dumped the contents of my SPROM, manually modifed (in my case, this
was changing the low-order board flags from 0x000f to 0x000e).

after a reboot, things sprang into life.

So... a heads-up. Whatever kernel is shipping with 8.10alpha6 (2.6.27-3)
would still appear to be broken.

My earlier offer to test and debug still stands... for the moment... now
that I got this working, I'm going to start using this machine soon...
so shout quickly if you want me to test anything :-)

best regards,
stephen
