Hi, Same issue on emachines E725
Tried different options in grub2:
acpi_osi=Linux, acpi_backlight=vendor and legacy, acpi=off
and none work out.

Maverick: 2.6.38-020638-generic
VGA: Intel Mobile 4 series IGP rev 09

When start ubuntu in 2.6.38, i cant see, but can go to gnome-command and launch the last command to setpci brightness to 77 and start to see !! and debug.
Then, when close the lid with 2.6.38, backlight turn off and on, normally. Brightness control still not work.
Only work setpci.
