Ok, thanks.

I understand. All I wanted is to see if someone would jump up and say 
something like: "Oh, no, this old version is known to be broken, you need some 
important bug-fixes that went into the updates". That obviously didn't happen, 
so I know what I am facing: Update to the latest version, test it thoroughly, 
and hope for the best :-(

Ouch. Unfortunately for our platform there is no reasonable chance I could 
move to a newer kernel anytime soon (still no mainline support) :-(

Thanks a lot.
