At Ubuntu 12.10, the brightness work, IF I load Ubuntu without using rEFInd at all. By using rEFInd it seems brightness does not work. Tested under 0.4.6 rEFInd.

If someone can test if using the pre rEFInd entry(press alt at startup, load 'windows' option) provided by a grub installed to the hd root(sda) the brightness work, and using post rEFInd interference linux entry which the brightness does not work; it can confirm the issue is rEFInd, not ubuntu.
