? Some fb drivers support the FBIO_WAITFORVSYNC ioctl (matroxfb and 
atyfb at least).

No.

I don't know what BSD secure levels do but I don't think so.

The mouse device depends on which input driver you use. ps2mouse driver 
needs access to /dev/psaux, /dev/misc/psaux or /dev/input/mice. keyboard 
driver needs read access to /dev/tty0 and rw access to the current vt's 
/dev/tty? device. You can replace both ps2mouse and keyboard drivers 
with the linuxinput driver which needs rw access to /dev/input/event? 
devices.
