In general, out-of-tree modules aren't compatible with linux-grsec. It
is not enough to simply rebuild them. It would require actively keeping
them compatible by maintaining patches for them and possibly working
with the upstreams for the out-of-tree modules for cases where bugs are
being uncovered rather than false positives / tweaks for compatibility.

Some out-of-tree modules aren't going to be compatible with the chosen
configuration at all, similar to how Xen support is disabled in favour
of having the hardening features marked as incompatible with it.

The NVIDIA driver and broadcom-wl need to be patched and and VirtualBox
is semi-incompatible with the chosen configuration. AFAIK, users would
need to rebuild the kernel with a couple options disabled for all the
VirtualBox features to work.
