Hi Bernd,

Sorry for the delay.  I'll start looking at this patch, but I first need to play with
it a bit first and get more familiar with that area of the code.

In the mean time, I looked for your name in the copyright assignment list, and don't find
it.  I think this patch is large enough to warrant one  Do you already have one in place?
If not, please follow instructions here:
