I figured out the same thing last night.  The reason why I added it to
initrd is because ext3 exists there.  Looking more closely at the
anaconda log, it wasn't able to find the xfs module.  I then added the
XFS tools and module to stage2.  Anaconda is able to find it now; it
even copies it to /tmp (same as other module).  The anaconda/loader
log indicates that it's able to find the xfs module, but it's failing
to load it (code 80).  Comparison of the modinfo information for both
ext3.ko and xfs.ko look exactly the same (kernel identification).

The xfs module is built manually.  I will try to build it using
rpmbuild from the kernel src rpm and try it.
