I cannot wait for exams ends, and I will have much more time.

I've implemented md5-based crypt but still having trouble with forcing
it to work properly.

In the meantime I found cpu implementation called "fast md5-crypt" and
want to analyze it and compare to the current one.
I tried to check coalesced read/write in sha256 crypt (because it was
easiest to do) and got following results:
Uncoalesced
Raw:    10569K c/s real, 10569K c/s virtual

Coalesced read
Raw:    12115K c/s real, 12115K c/s virtual
+4.6%

Coalesced read and write
Raw:    12376K c/s real, 12376K c/s virtual
+2.2%
Overall: +7%

It is not a big deal, but it's worth to do in other patches. The
problem is that it makes code harder to understand/manage, but I
should find a way to improve that.

Surprisingly I didn't stated any difference in coalescing operations
inside kernel.

I have also added gtx460 benchmarks results to the wiki.  Presenting
them as a list its not user friendly, so meaby we could turn on html
or php support on wiki to add charts as a nice google chart script,
example here:
