The program you refer to is not a program but the fedora smp kernel
I have yet to get the fedora core 1 smp kernel to boot with intel dual
xeon server. Someone said you can compile an smp kernel from
pristine sources from kernel.org
and it will work, but there are
specific instructions to do so.
I opted to wait until sometime this month when Fedora Core 2 is
released with the 2.6 kernel and try core 2's smp kernel.
Why the Fedora smp kernel doesn't work on dual xeons on some boxes and
Redhat 9's works is still a mistery many people have been unable to
solve. With the release of Fedora Core 2 around the corner, I don't
expect this problem will ever be solved with the core 1 smp kernel.
