Our assumption that most distros issue STANDBYNOW seems wrong.  The
upstream sysvinit and thus many distros including gentoo and opensuse
don't take any action for libata disks on spindown.  We can skip
compat handling for these distros so that they don't need to update
anything to take advantage of kernel-side shutdown.

Jeff, I think we can avoid a lot of problems with this.  Those distros
which didn't do anything on shutdown would still cause emergency
unload on older kernels but at least it isn't a regression and things
should just work on newer kernels.

If you ack this, I'll update the shutdown.html page accordingly.
Thanks.
