I'm running a RELENG_7 kernel and a userland as 7.0-REL on one of my laptops; I've been asked to check if a given driver problem in RELENG_7 is as well with HEAD... can I update the kernel to HEAD and let the userland (and all my compiled ports) as 7.0-REL; I know that this is not the intention, but it would cost me a lot of work if I should compile as well ~200 ports....
As a general rule, running old userspace on a new kernel works pretty well, but you should expect certain types of things to not work -- for example, monitoring tools that expect the kernel layout of data structures to be unchanged. Within a particular -STABLE branch this is a bit less volatile, but as you go from, say, 6-STABLE to a 7-STABLE kernel, the chances that some of the more obscure options to netstat, etc, will not work are pretty high. Likewise, be careful to disable any third-party kernel modules that may require recompiling but aren't caught by the base system build, or you'll get a nasty surprise when they panic. :-)
