Following the features for python I propose to add extra feature for kernel-modules installing (like fo nvidia-drivers). Very often I am using different versions of kernel. For each I have to reemerge nvidia drivers to get module working. I know it is easy to manage modules manually, but I think it would be nice to do it automatically. My proposition is to add extra USE flag for kernel sources, for example 'multiversion' flag. This USE enables installing modules for each kernel version found in /usr/src/linux-* not only for /usr/src/linux. Without this flag set emerge will install module for actual /usr/src/linux. I think it would be helpful for many users.
Am I reading this correct that the USE flag would be in the module ebuild and nothing do with the kernel ebuilds?
What do you do when a kernel module only compile against some versions of the kernel sources present? Or only some of the sources present are configured/built etc.
