please let us use the l4-hackers mailing list for further discussion.

Indeed we ported Valgrind to Fiasco.OC and L4Re. Its source code is 
available in the L4Re SVN in l4/pkg/valgrind. As you might have noticed, 
our paper was in 2010 and if I remember correctly, the Valgrind version 
in the repository was last updated around 2011. It might still work, but 
you may also encounter problems. Feel free to try this out and let us 
know about any questions you have.

Apart from that there may be other ways of achieving your profiling 
needs on top of Fiasco.OC. What exactly would you want to do?

Kind regards,
Bjoern
