Not as easy on the Classics, but it seems to me there is plenty of room on the NG EICAS display to get detailed Pressurization system info. The NG is unique in that the EICAS has very little to do with Crew Alerting (with the exception of specific engine warnings, everything else is through the master caution and annunciator panels), I don't see why it couldn't be reprogrammed to add non-normal config advisories/warnings as with the rest of the Boeing line.
