Not across major version numbers, no.  You'd have to re-compile all of the
programs linked against libqt.so.1.  (Assuming that they will recompile --
some of the differences between the two may not allow this to work.)

Probably the easiest solution, assuming that you actually need qt 2 for
something, is to install both.  (You may have to give a --force flag or
something similar to rpm, but you can do it).  This way, all of the apps
can find the appropriate library version, and everybody's happy.
