I'm a forgetful old git. In my world it usually goes like this:

emerge, build, install new kernel
carry on with work
boot into new kernel at some later point
observe xdm doing nothing on-screen
curse and swear mightily
Ctrl-Alt-F1
login as root
check symlink
module-rebuild rebuild
modprobe -r nvidia && modprobe nvidia
/etc/init.d/xdm restart && logout

takes about 6 minutes total, 6 minutes that I'll never get back :-)
