Description
I can no-longer change the brightness or turn on/off the wireless interface from the keyboard on my asus eeepc. This is a regression. It worked some time in the past, and I just noticed it when my wife turned off the wireless card in Windows and I could not turn it on in HAIKU.
There is a forum thread on the issue:

I'm on hrev46523 and i can't still change brightness/other things using the keyboard on my laptop. Was possible long time ago.

Update: if on my laptop i press the fn key + F7/F8 (keys to change brightness), as i've said, nothing happens. But inside the syslog i can read:
KERN: [ACPI Debug] String [0x0B] "FN+F8 Event" KERN: [ACPI Debug] String [0x0B] "FN+F7 Event" KERN: [ACPI Debug] String KERN [0x0B] "FN+F7 Event"
What that means?

This is a duplicate of #8258.
The only reason it worked before was that BIOS was handling your brightness, so it is not really a regression, but an unimplemented feature. BIOS handling gets disabled when ACPI starts. A driver for handling brightness has never been fully implemented. It's not very complicated, while it is on my TODO I can't do that until I have Haiku working on my laptop.
The debug output I'm not sure about, I think Jerome added some debugging info.
This ticket can be closed, the issue has been resolved in recent nightly images.
