You will have lotsa modules now with 2.6.
But all depends on what is there. I nuke ipv6 modules (they are re-installable) and OSS (open sound system) and some agp stuff as my nvidia stuff dunnah like agpgart or via_agp
There is a blacklist of modules you never want loaded at startup. Hotplug and discover will load eveyrthing under the blooming sun right now. Blacklists for each one :)... Fun eh?
