What would you prefer the commit message to say? I was only explaining why the
patch was needed.

I need to fix formatting anyway, as Sergei has pointed out, so either I rework
this or you revert as originally planned and I'll resubmit the original patch
for the SB600 only, whichever works best for you, I'm aware time is an issue
here.

I didn't include Markku as I'm not sure I should be adding people to the
Commit without their express permission.

I'm still quite new at this so sorry for causing all this trouble.

Regards
Darren
