In this case setting osrelease to 2.4.20 will not result in a fully working application. You could pray and set osrelease to 2.6.16. Maybe it works for you. But don't be surprised if it doesn't work for you. We have known problems here. If you started an application with 2.6.16 I recommend to reboot if you want to switch back. I've seen cases where old linux stuff was still in memory even after a program stopped. This results in a panic if you switch the osrelease version (not immediatly, a few seconds after switching).
