The base kernel footprint is quite observable in VM = configurations, where it's common to configure quite low memory = footprints -- 256M, 512M, etc, in order to improve VM density. Speaking of memory - does loading something as a module impact on memory = consumption by the kernel (one way or the other)? ie would it be a penalty to load stuff as a module, especially if you = start loading 10's of them.
