:-) I for one would find it useful (even after I have gtk3 on the machine).

That's interesting.  I'll definitely take a look at the documentation you
mentioned.  Then again, if the full fix isn't too far away I may just stick
with 3.3.5 until that becomes available.  That probably comes down to how
much time Takashi has.

I'll look into this too.  I would need multiple such firmwares to cope with
different configurations (they are sometimes switched on the fly) but like
you said, it would be another interim solution.
