Why would the tables have to be in the kernel?  Even if they are in the
kernel, what is stopping something loading the correct table on boot
based on some userland tool run out of /etc/rc.d? I'm also not sure what
the benefit to having the tables in the kernel would be.  A userland tool
which watches the data from the sensors (however they are presented, whether
it is a sysctl MIB or data passed via RFC 1149) and acts appropriately
would appear to be a more flexible solution (ala devd)
