I just tested on SABRE SD to remove the possibility that one of
our kernel patches was coming into play and found the same result:

root@imx6qsabresd:~# cat /proc/cmdline
video=mxcfb0:dev=hdmi,1920x1080M@60,if=RGB24 video=mxcfb1:off 
video=mxcfb2:off video=mxcfb3:off console=ttymxc0,115200 
root=/dev/mmcblk0p2 rootwait rw
root@imx6qsabresd:~# cat /sys/class/graphics/fb0/mode
U:640x480p-60
