ah if you say so, I trust you :)

yes, I see it at r8510

Yes, as a Debian developer I have access to a porterbox of any
architecture we support, so I can do any test/recompilation and so you
want. I can understand that using me as a proxy might be a little bit
tedious and slow, so if you prefer to have direct access I have to ask

Just let me know: I'm fully available for you.
