Hi, Antonino.

I am still getting warnings on depmod with the 2.6.18-rc2 kernel:

INSTALL sound/usb/snd-usb-audio.ko
INSTALL sound/usb/snd-usb-lib.ko
INSTALL sound/usb/usx2y/snd-usb-usx2y.ko
if [ -r System.map -a -x /sbin/depmod ]; then /sbin/depmod -ae -F System.map
2.6.18-rc2; fi
WARNING: /lib/modules/2.6.18-rc2/kernel/drivers/video/backlight/backlight.ko
needs unknown symbol fb_unregister_client
WARNING: /lib/modules/2.6.18-rc2/kernel/drivers/video/backlight/backlight.ko

You posted a patch here a few days ago for 2.6.18-rc1-mm1 which fixes this
issue. Basically, the USB Apple Cinema display driver selects backlight
support, but backlight needs some things from framebuffer, which is turned
off. Kconfig does not recursively select CONFIG_FB, so backlight ends up with
unresolved symbols.
