That just means the problem is a software rendering fallback path, but it
doesn't show which one. You'd need to make sure at least the X server binaries
are compiled with -fno-omit-frame-pointer and have debugging symbols.

Not sure, but my guess would be
http://cgit.freedesktop.org/xorg/xserver/commit/?id=45ebc4e3fac7f1a85167d05e2833949b89f02d64
or one of the commits surrounding it.

That would be interesting.

> If yes, will that commit be backported to the 1.16 branch?

I can't predict the future, you'll have to nominate it and see. :)
