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
needs unknown symbol fb_register_client
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.

The patch is still in the -mm tree. They're all in Ottawa right now, so this
will have to wait.
