Goal is to run a system maybe longer than a year!!! If the patches are applied to a loadable kernel module only, then it should (at least in theory) be enough to rebuild/install the kernel as usual and then just reload the kernel module instead of rebooting. Reloading the module requires that the given service is not in use, which is why it may be easier to just reboot. Taking this idea to the extreme, there is a number of other projects, non-FBSD, that work on micro/nanokernel technology. I can't recommend you one over another - I haven't tried them - QNX is a commercial product, also there is open-source LSE/OS, just to get you started.
