the results you just posted appear to show a 20% slowdown for function 
calls, and a 10% speedup for exceptions.

both things were optimized at the sprint, and the improvements were 
confirmed on several machines.  on my machine, using timeit on the test 
bodies, I get noticeable speedups for both tests; from my earlier post:

function calls:

>      25 usec per loop for Python 2.4.3
>      22.5 usec per loop for Python 2.5 trunk

try/except:

>      15.1 usec per loop for Python 2.4.3
>      23.5 usec per loop for Python 2.5 alpha 2
>      11.6 usec per loop for Python 2.5 trunk

maybe the function call issue is an AMD64 thing?  or a compiler thing? 
do you see the same result on other hardware?
