haven't you just got kernel 2.6.15-20? or what packages are you talking 
about? might be if a heavy load of packages has landed on your machine, 
and the changes are so heavy that the instructions on how to 'reload' 
the configuration might be too exhaustive.

but more enlightened people might help, if you specify what packages 
exactly you installed that requires a restart.
