Heads up! (if you're running a modular kernel)

[Paul Goyette <paul%whooppee.com@localhost>]

Somewhere around 7.99.39, with the changes to the routing socket 
messages, a slight amount of breakage has occurred!

If you are running a modular kernel from 7.99.39 or newer that does 
_not_ include the compat module (with COMPAT_70) built-in, an 
ifconfig(8) image from earlier than 7.99.39 will fail.  Loading the 
compat module does not help, since it does not include the sysctl 
sub-tree(s) that ifconfig uses.

If you want to mix a newer kernel with an older ifconfig, you must 
ensure that your kernel includes the COMPAT_70 code built in.
