yes.  but it is strange to see a bunch of output to stdout, none of
which contains the one thing you might be interested in.  perhaps
having both printf and uprintf would do the trick.

yes, it is correct.  I tracked down the problem to mount_xfs.c, and
then created a patch (included at the end of this message) which improves
things significantly.  The hard-coded 17 is what was breaking things.
With this patch, you no longer need to run modload by hand, the call to
vfsload() takes care of everything.  The only limitation is that now the
xfs_mod.o file needs to be in a place where vfsload() can find it, namely
in the /lkm directory.  If you install this patch, you'll have to update
the instructions in the INSTALL file so that they reflect the new reality.
