I indeed use VirtualBox, but as of this moment, I have disabled the
loading of the kernel module. The box still gets stuck and for unknown
reason, ALL(!!!!) CURRENT systems (different generatins of hardware,
with or without integrated GPU) show question marks on the screen and
no usefull screen when vt is enabled and in backward vga compatible
mode. This also happens with nVidia dedicated PCIe GPUs as well as with
Ivy Bridge integrated IGP 2500.

The port virtualbox-ose-kmod is compiled everytime I compile a
kernel/kernel mods via 
PORTS_MODULES="emulators/virtualbox-ose-kmod"
in /etc/src.conf.

This unmature vt stuff starts to bother.
