You're probably right, for the various very special keys like touchpad
toggle, video mode toggle, etc. there is no handling available outside
of acpid. However, keys for WiFi/bluetooth toggling, volume, brightness
and media player control should work without any acpid help. I cannot
verify that for every Asus Laptop, of course.

Also, sorry for being so inconsiderate in the OP.

Title:
  Brightness hotkeys misdetected on Eee Pc

Status in “acpi-support” package in Ubuntu:
  Triaged

Bug description:
  The acpid scripts that ship with acpi-support misdetect the brightness
  keys on the Eee PC 901 (and probably most other models, as the ACPI
  events are very similar). Both keys, brightness up and down, are
  detected as brightness down. On the other hand, brightness events are
  already handled by eeepc_laptop, so any additional handling by acpi-
  support is harmful and results in crazy behaviour if one presses the
  keys. Removing the acpi-support package solves the issue.

  But, the real WTF is, why does Ubuntu *still* ship acpi-support, and
  acpid? The hacky scripts it uses are largely outdated and cause more
  issues than they solve. ACPI events, bare for a few exceptions, are
  now handled either directly by the kernel input layer, or other
  subsystems, like UPower.
