Using 9.1 RPMs on 9.2

I notice that many packages which were available on 9.1 are no longer available from SuSE on 9.2, e.g., snort and nessus. Would it be safe to download the 9.1 packages (snort.rpm and nessus-core.rpm)? Are there any plans to increase the number of 9.2 packages available? Thank you, Lucky Leavell
