On my OI installation I get the following list for the io provider:

[ewer at solewer:~/Documents/RefCards]$dtrace -l -P io
   ID   PROVIDER            MODULE                          FUNCTION NAME

[ewer at solewer:~/Documents/RefCards]$uname -a
SunOS solewer 5.11 oi_147 i86pc i386 i86pc Solaris

It's the same list as on a Solaris 10 sparc system.
