Yes, /etc/src.conf uses WITHOUT_* on a per-module basis, so you need
to explicitely name the modules not to build.

But you're right, there's only WITHOUT_USB (for not building the
USB-related parts), so going with kernel configuration would be
a good point to start -- the more precise you can define your
test setting and its variables, the better you can diagnose the

In /etc/make.conf, you could use MODULES_OVERRIDE to define the
set of modules you want (because only _those_ will then be
build) and keeping their functionality out of the kernel. In
this case, you have control over your test setting using the

The same files offers NO_MODULES=yes to avoid building modules
at all (use custom kernel instead).

If you decide to use WITHOUT_MODULES, you can define the set of
modules you want to avoid building, everything else will be

No, /etc/src.conf as (according to its manpage) a defined set of
variables that will be considered when building (or _not_ building)
certain modules.

That's a good setting for using a custom kernel and not even
building the modules for the non-used functionalities. :-)
