Well AFAIK kldstat -v should return them all...


Also, as a side note to your question, find below an excerpt from ucom's
man page:


SYNOPSIS
     To compile this driver into the kernel, place the following line in
your
     kernel configuration file:

           device ucom

     Alternatively, to load the driver as a module at boot time, place the
     following line in loader.conf(5):

           ucom_load="YES"


So indeed if you want it statically in the kernel, you need to add
"device ucom"


Have you tried doing that, building again then querying again with
kldstat -v ?
