Since no one else confirmed this, I will. Yes, having userland and the
kernel out of sync is doesn't always work, and hence not supported, a
bad idea and something you shouldn't do.(*)

Things in userland depend on things in the kernel, and if the two get
out of sync, you can get problems. It doesn't even have to be userland
source. I was getting screwy console behavior because the console
device in the kernel was out of sync with the userland termcap entry
for the console.
