Luis recently committed a patch adding basic support for BookE hardware
watchpoint:
http://sourceware.org/ml/gdb-patches/2008-08/msg00087.html
You would also need this fix from Ulrich:
http://sourceware.org/ml/gdb-patches/2008-08/msg00321.html
And Luis' kernel patch which is mentioned in the first link. It will
show up in 2.6.27.
I don't know about the software watchpoint issues...
