Hi,

on latest intrepid and vaio BZ11XN (X4500MHD) :
 - sudo /etc/acpi/sonybright.sh {up|down} works, but only after "xrandr … CONTROL=native"
 - xbacklight works, with xrandr previously called too (but not without)
 - Fn-keys produce nothing for LCD (but work for sound), and I attached my acpi debug info to bug https://bugs.launchpad.net/ubuntu/+source/acpi-support/+bug/251665 but I think it was missed because the bug is fixed for original poster and not for me, though we had the same problem.
