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?)
