Sorry, I just retested the acpi_backlight=vendor parameter in grub, and with the latest updates its working perfect.. The last time I've tested was in jaunty. This really fixed and works perfect.

I've just updated my /etc/default/grub with that option and the changed line its just like this:
GRUB_CMDLINE_LINUX_DEFAULT="quiet splash nomodeset i8042.nomux acpi_backlight=vendor"

Just to explain:
- nomodeset: makes something show up in the screen (fix the videodriver)
- i8042.nomux: makes the touchpad button work.
- acpi_backlight=vendor: fix the brightness problem.

Now just do the update-grub cmd. Remeber that this changes need root privilegies, so "sudo su" or "sudo <cmd>"
