I CC Aleksandr and Ed, both developers of vt(4) and Alexey, the
maintainer of the NVIDIA proprietary driver in the Ports tree.

To sum up the thread: Matthieu is having trouble with vt-switching when
using his NVIDIA Quadro card on FreeBSD 10.1-RC2. No matter if he uses
syscons of vt(4), he always get a blank screen when switching to the
console. Exactly, like syscons with a KMS driver: the console works (ie.
responds to keyboard events) but nothing is displayed.

A friend of his has a similar problem on 9.3.

Have you guys already heard of Mathieu's problem? Did we already get
success/failure reports from owners of Quadro cards?
