After checking some other bugs that are related with my problem i decided to open a new one because the solutions referred there didn't work for me and there may be some other issues that i am missing.
After the installation i was seeing "atkbd.c: Use 'setkeycodes e01e <keycode>' to make it known." output at the dmesg. I tried ti fix it but it didn't help me set the brightness.
I will add the step by step procedure of what i did at this report.

The main problem is the nonworking of brightness function keys, fn+f4 and fn+f5. I am using Ubuntu Hardy with a Gnome desktop. It is a fresh install and i have the doubling problem reported in <a href="https:/ /bugs.launchpad .net/ubuntu/ +source/ hal/+bug/ 239706">#239706</a> and in <a href="https:/ /bugs.launchpad .net/ubuntu/ +source/ hal/+bug/ 207473">#207473</a>, though the solutions didn't work for me.
