Yes, although around these parts we tend to use pciconf -lv.  You have 
an AMD Radeon HD6300.

vt(4) is the KMS-aware system console.  To use it, enter

   kern.vty=vt

in /boot/loader.conf.  It will take effect on boot.

The problem of leaving X and having the screen stop responding is due to 
the old system console not understanding kernel video mode switching. 
vt(4) is the new console.  See 'man 4 vt' for more information.
