Good.
I tested upstream version (bcc62fb) and got on all my machines the
same bug (same Kernel binary started on all):

I haven't tried 3.4. These seem to be new issues. I will try 3.4
soon, but
could you try stable 3.3.6? Stable 3.3 up to 3.3.4 is known to work on
various machines.
all logs attached for the 715/64, B160L and C3000 machines.
I'll test tomorrow your patch (but will try to update my binutils/
gcc prior to that).
There are known issues with GCC 4.3 branch. In particular, the
delayed branch support
is broken (at least three different bugs). I would suggest you
install 4.6.3 from shirka
or magnum.
