Ah, ok, might be. I took one from gentoo as I assumed the config might fit the gentoo-sources better somehow (although I still don't know what patches are applied to vanilla-sources to get gentoo-sources ... I just thought the config might somehow make use of those changes). > These should provide everything you need to boot, and most everything > else as modules, which will be automatically loaded.

I don't look for those last milliseconds, I just want to get rid of some old stuff I might drag along for years already ... Thanks, Stefan
