kernel modules are CONFIG_PROTECTED, so they are not automatically removed when you uninstall / remerge the package (you have to remove them manually), so you just have to remerge the package after you change the /usr/src/linux symlink there is also the module-rebuild utility, that automatically remerges packages that installed a kernel module i.e. ln -sfn linux-VERSION1 /usr/src/linux module-rebuild -X rebuild ln -sfn linux-VERSION2 /usr/src/linux module-rebuild -X rebuild ... you might have to do module-rebuild populate before the first time... yoyo
