Not really. I was thinking of PowerPC and Solaris, as there already
exists a opensolaris
community for porting opensolaris on PowerPC. Honestly speaking I have not even
tried to see the Power PC solaris code yet. But first I would like to
know the internals
of  Dtrace on x86(or any one architecture) before proceeding any further.

If so,can you
please share their email ids.
