C3000 has dual-mode firmware so you can run either 32 or 64-bit kernels on it. Actually, Ryan just committed a patch to let 64-bit kernels work on machines which only have 32-bit firmware, so you can now run 64-bit kernels on machines all the way back to the C160 (not the C160L!). You should prefer a 32-bit kernel over a 64-bit kernel for the moment on a C3000, unless it has more than 3.5GB of RAM or so. It should be faster (want to produce some lmbench runs to demonstrate this?) -- "Next the statesmen will invent cheap lies, putting the blame upon the nation that is attacked, and every man will be glad of those conscience-soothing falsities, and will diligently study them, and refuse to examine any refutations of them; and thus he will by and by convince himself that the war is just, and will thank God for the better sleep he enjoys after this process of grotesque self-deception." -- Mark Twain
