OK maybe it's just the extra driver probe time then.

Well I've been just using omap2plus_defconfig with:
# modprobe tsc2005
# modprobe gpio_backlight
# modprobe panel_sony_acx565akm
# modprobe omapfb
# echo 255 > /sys/class/backlight/acx565akm/brightness
And then the following to blank for idle:
# echo 1 > /sys/devices/platform/omapfb/graphics/fb0/blank
But in the world of eternal regressions, I'm not seeing anything
on the framebuffer with v4.6-rc2 :( No idea what broke it or when
as my n900 is in the rack.
Anyways, below is also my lsmod output.
Regards,
Tony
