Oh, no sorry I screwed and I tested for different test vectors... time
to go sleep.

3770k:
./run/john -test -format=PBKDF2-HMAC-SHA512
Benchmarking: PBKDF2-HMAC-SHA512, GRUB2 / OS X 10.8 [PBKDF2-SHA512
128/128 SSE2 2x]... DONE
Raw:	190 c/s real, 192 c/s virtual

./run/john -test -format=grub
Benchmarking: grub, grub [PBKDF2-SHA512]... DONE
Raw:	129 c/s real, 129 c/s virtual

Bull:
./run/john -test -format=PBKDF2-HMAC-SHA512
Benchmarking: PBKDF2-HMAC-SHA512, GRUB2 / OS X 10.8 [PBKDF2-SHA512
128/128 SSE2 2x]... DONE
Raw:	180 c/s real, 180 c/s virtual

./run/john -test -format=grub
Benchmarking: grub, grub [PBKDF2-SHA512]... DONE
Raw:	74.2 c/s real, 74.2 c/s virtual


Anyway looking at the results on 3770k it does not look so bad, and
maybe we can use that code anyway.

Sorry for inconvenience,
Lukas
