Yes, the modules names aren't always exactly
the man page name.  Stubborn & inventive
use of apropos & locate (& reading through
stuff in /usr/src/sys/modules/ ) can help, but
not everything is obvious.

ahc(4) covers the first few.

libalias(3) appears to be the only thing to even
parenthetically mentions cuseeme (NB I didn't
run grep over the whole dang filesystem, though).

Most of the if_something are under something(4).

For the geom_blahblah, see if it's covered by something
mentioned in the SEE ALSO sexion of geom(8) or geom(4).

Good luck.
