Running Solaris 9 on Ultra 20

Has anyone tried to install Solaris 9 x86 on the new Ultra 20? We have a proprietary application that will not run under 10. I've looked all through Sun and only see 10 as certified. However, it doesn't state that 9 can't run on the box.

You must've got through to the wrong forum as this forum is only for issues or questions concerning the Sun Update Connection application. Please try another forum as any answer we give you will only be a guess.
