Hello,
Sorry for delay. d945cb9cce20ac7143c2de8d88b187f62db99bdc is not the first bad commit as I've managed to make 
kdesu work simply adding some senseless instructions to pty_write_room(). Anyway.

As for kdesu, it's obvious that kernel should be free from code that simply makes some buggy user space 
programm working (even one that was working for years until 2.6.31).
Lots of versions could be affected (4.a.b, 3.c.d, ...) and I'm just not sure that all of them will be
updated ( not all, but popular ones. like 3.5.x ). We'll see.

Thanks,
	Sergey
