Usually programs do LD_ASSUME_KERNEL=2.4.9 when they use the old LinuxThreads
and not NPTL.  glibc 2.4 removed LinuxThreads support and only supports NPTL. 
Unless you can get a newer version of the software which uses NPTL, you can't
run it with FC5.  You might be able to run the software with VMware, Xen, or a
chroot to an FC4 or earlier environment.

There is a useful page, http://people.redhat.com/drepper/assumekernel.html,
which talks about LD_ASSUME_KERNEL and the different values and what they mean.
