Didn't the VESA drivers require kernel code to switch to V86 mode to call int10h going all the way back to the 90s? Kernel mode setting might be new to a unform interface for graphics drivers, but using kernel mode (ring0) code to switch graphics modes goes back to the early beginnings and the simplest drivers.
