I have made my Gentoo working without PAM. I didn't test xlock before, but then I found I couldn't log in with my password. So I changed to vc1 and killed xlock.
After looked into xlockmore (xlock's package name), I understood I needed to enable xlockrc use flag.
Ran it from command line, I was prompted for entering key (the password):
Now session lock is back.

$ xlock -mode blank Key: Again: $ cat .xlockrc Something
