Comment 56 for bug 810093

I have a good news and a bad news.
Good news:
Backlight changing is for me now working as expected.
Bad News:
Loading the kernel module is changing the backlight when it is loaded

I think the problem is somewhere in the quirk detection. I tried to find it some time ago and came up with the solution from #25.

I just created this patch for the backlight module. The patch is against current ubuntu oneiric linux source and includes min max corrections. With this patch it isn't necessary to detect the quirk, because we are using the special behaviour of the backlight controller on minimum.
