Thus wrote Stephan Krings:
Same for me, although the Fn-keys for changing the display brightness
no longer work, when DRI is enabled in XFree86. But I guess this has
nothing to do with ACPI but is a problem with the XFree86 driver for
Radeon cards.
I wouldn't be so sure -- I have an Asus L380C with a Radeon M7 and I've
had no problems changing brightness so far, be it with, or without DRI.
