I tested the new version and here are the benchmarks:

OpenCL 64-bit 
./john -test=15 -format:NT
Benchmarking: NT MD4 [OpenCL 1.0]... 
OpenCL platform: <<< Apple >>>
OpenCL device: <<< GeForce 9400M >>>
DONE
Raw:	9127K c/s real, 21100K c/s virtual

64-bit
./john -test=15 -format:NT
Benchmarking: NT MD4 [128/128 X2 SSE2-16]... DONE
Raw:	24121K c/s real, 24137K c/s virtual


OpenCL SSE2
./john -test=15 -format:NT
Benchmarking: NT MD4 [OpenCL 1.0]... 
OpenCL platform: <<< Apple >>>
OpenCL device: <<< GeForce 9400M >>>
DONE
Raw:	9313K c/s real, 21906K c/s virtual

SSE2
./john -test=15 -format:NT
Benchmarking: NT MD4 [128/128 SSE2 + 32/32]... DONE
Raw:	14783K c/s real, 14793K c/s virtual


Big increase in benchmarks.  It should work really well on a high-end video card.
