qt4 i386 on FC6

[David Jansen]

A user at our institute has a program that comes as a binary rpm, and
needs qt4. But the program is built as a 32-bit executable, and the
computer is a 64-but system. Now there doesn't seem to be a i386 rpm of
qt4 in Fedora Extras for FC6. Does anyone know why?
I noticed the i386 package exists for Fedora 7 so maybe an upgrade will
do the trick, but on the other hand, the makers of the program told us
it was only tested for FC5, FC6 and RHEL4 so maybe we will run into a
new set of problems after the upgrade.
Would installing the qt4 package from an fc6 i386 repository be
compatible or are those packages different from the i386 packages in a
x86_64 repository?
