I have the same problem on an eeePC 1215N, Ubuntu 13.04 32 bits.

I found a workaround to get maximum brightness back:
sudo setpci -s 00:02.0 f4.b=ff

It resets the maximum brightness to maximum.
If it does not work for you, try another PCI device (find the adress with 
lspci), like 
sudo setpci -s 00:02.1 f4.b=ff

Status in “gnome-settings-daemon” package in Ubuntu:
  Confirmed

Bug description:
  if windose 7 to maximum brightness. then reboot then everything is OK.
  You can set maximum brightness. If after reboot of Ubuntu in Ubntu.
  then the level of intensity that was at a minimum - is maximized. and
  the brightness decreases from this level. ie if you set it on the low
  level to discern that what is at all unrealistic.
