Your log doesn't seem to have anything to do with any of those bugs, or,
for that matter, Debian bug #407875. Please open a new report when you
have a different problem (if the backtrace printed in the X log is
significantly different, as is the case here, chances are you're hitting
a different bug).

That's surprising, given that the backtrace you included below doesn't
seem to be related to the code this patch touches.

Never. Etch will release with xserver 1.1, lenny will have xserver 1.3
when etch is released.
