    Thanks to all that replied, I now have it all working with the latest
 build 1232 *and* gcc 4.1.1 .  I had tried the earlier gcc versions, 
but then had problems building uClibc.  Aggghhh.

All it took was to comment out these lines in the /etc/init.d/S30bluetooth 
file:

#       echo -n "Starting 32kHz clock..."
#       /usr/sbin/pxaregs OSCC_OON 1
#       while /usr/sbin/pxaregs OSCC_OOK | tail -n 1 | grep -q -v 1;do
#               echo -n '.'
#               sleep 1
#       done
#       echo "Settled"

    Crude, but it works. 8-)

    Here is the output of the pxaregs line after a clean boot and 
bluetooth up:
