Comment 116 for bug 333386

I'm sorry to bother...

Yesterday I accepted the updates proposed by the Update Manager, which
included a kernel update (version 2.6.28-15.52) and the brightness problem
came back.

(I know I should have known it could happen but... I have already done it)

The main problem now is that I don't knok how to go back.
I've tried to install the patch again but the package installer says that
there is a newer version installed and doesn't proceed.

I'll thank you any help
