[syslog-ng] Integrating syslog-ng on Solaris 10

Hi On Solaris machine the legacy logging is done by SMF system-log. And there are many Solaris SMF which depends on system-log SMF. If I want to integrate syslog-ng to Solaris box , should I disable system-log SMF ? But disabling "system-log" will cause few legacy SMF to go down. I can't have system-log SMF and syslog-ng enabled at the same time since it would result in logging twice. Can any one suggest alternative approach for integrating syslog-ng to Solaris box.
