As an alternative to using VT IOCTLs you should be able to echo these values to /sys/class/graphics/fb0/blank and blank the screen. The attribute is pretty new so it hasn't had a lot of testing on the various fbdev drivers.
#define VESA_NO_BLANKING 0 #define VESA_VSYNC_SUSPEND 1 #define VESA_HSYNC_SUSPEND 2 #define VESA_POWERDOWN 3
