One other oddity is that the new kernel seems to automatically add routes
when you bring up interfaces.  I had to modify my initscripts to not do
'route add -net ....' because the 'ifconfig eth0 ....' was doing it
*automatically*.  If I downgrade to 2.0.36, with the same ifconfig, route,
initscripts, it doesn't do this...
