I figured it out. These ioctls are:
#define TCGETS _IOR('t', 19, struct termios)
#define TIOCGWINSZ _IOR('t', 104, struct winsize)
I'm guessing that since I redirect stdout to /dev/fb0, Linux is treating /dev/fb0 as a terminal, and therefore it's receiving terminal ioctls.
Is this something that fbdev should be supporting, or am I wrong to use /dev/fb0 as a terminal?
