Backward vs. forward compatibility discussion aside, there is a reason
why most (all?) distro kernel packages run depmod at *install time* on
the target machine. There might be modules installed by other packages,
the format might change, newer depmod has a configuration file and
finally the files are not exactly small and can be recreated rather
easily. It might be a good idea to do the same when compiling kernels
manually and copying them around.
