Sorry for my delayed reply, but wasn't earlier possible.
Yes, of course, as long as I have the hardware available I can do some tests, even
on a recent kernel due the fact having the project so far completed, just another
test run on the 9th of December.

Due the flood of emails I lost now track which version You would be interested in
and maybe also which kernel version, so, please let me know and maybe were I may
download the patches.

Should be not a problem at all.
