Thanks. However, since I can't easily test the older kernel versions I
don't feel confident in changing the old legacy paths. However, I'm
sure we can make the paths that are currently in use more sane. Here's
a list of /sys paths used by omhacks grouped by the command(s) that
access them. It tries these in order and picks the first one that is
found.
