My proposal would also work because every file that contributes to your kernel source has a revision tag. It follows that the most recent tag date across all of those files describes the most recent commit in the repository that lead that that kernel. It's probably sufficient just to look at src/sys/ to determine a date that's close enough to support from. It requires no CVSROOT or cvsup or cvs hackery and requires just a short amount of extra time (1.5 minutes on my -current laptop) which is nothing compared to the length of a normal build with all the modules and everything. Let's have it switch-off-able in make.conf, and advertised in the kernel version string.
