Whether it's safe to run software that isn't frame buffer device aware on a
system using frame buffer devices heavily depends on the graphics hardware and

XF86_SVGA assumes your graphics chipset is in VGA text mode. If this isn't the
case (you're using frame buffer devices), unexpected results may happen. I
don't think fbcon can be blamed for that... Banging the hardware from user
space can be riskful.

Alex: as the fbdev HOWTO maintainer, you should know better :-)
