But is it really enough? modpost needs all modules to extract symbol versions so it means kernel-source should actually ship all module.o files. > Ah. In that case, I suppose it's all moot and won't end up being an issue.

Mandrake and AFAIK RedHat ship single 2.4 kernel source that allos building external module for any currently running distribution kernel. While this could be tweaked using symlinks it means that kernel-source needs to be shipped with copies of vmlinux and *all modules.o for every kernel flavour in distribution. As of this writing Mandrake includes 6 or 7 kernel versions. It is rather too much :( So it is still an issue. I am thinking about some way to direct modpost to extract versions out of /boot/vmlinuz and /lib/modules if it detects pristine distribution sources To recap - currently under Mandrake and RH it is possible to do rpm -i kernel-source cd /external/module/src make and it will automatically create module for currently running kernel as long as kernel is distribution kernel without any extra configuration. It appears that to support same functionality on 2.6 modversions need to be disabled ...
