Please share the beast model :P (or maybe ive missed it). 
in kernel config You have multiple option for backlight eg. for thinkpad
there is extra one in "thinkpad specific acpi" maybe You have something
similar for Yours stuff.

And (its only my private opinion - could base on wrong facts :P) dont be
used to hal because the 1.8 xorg-server dont like it any more,
preferring udev, and future versions wouldn't probably support hal at
all.

Lately i delete hal USE and now iam using udev - excepting auto mounting
usb stick etc.

You must exorcise any evil proprietary operating systems that possess
any of the computers under your control, and then install a wholly/holy
free operating system, and then only install Free Software on top of
that.
