And btw, these days there's usually not much point in removing usused drivers from your kernel, it won't boot noticeably faster and the amount of ram/diskspace saved is only relevant in (some) embedded setups. So all that's left is another opportunity to shoot yourself in the foot... :) HTH, Juergen
