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).

Bye,
Alexander.
