Hello guys

I didn't get much feedback on my question about the banks (so sorry for the bad line wrapping), hence it's probably best to submit the patch without bank support for review and go from there. I hope it's OK to amend the copyright line, otherwise that can just be scrapped.

The FIXME comments are where things might have to be straightened out. This will probably require a few iterations but I'm happy to follow whatever advice you have.

Best regards and thanks.

Matt
