No i think thats not enough because not everyone is using the ACPI video
extension at this moment and at least for my ThinkPad X61 i got:

babyface@bart:~$ ls /proc/acpi/video/VID
CRT0  DOS  DVI0  LCD0  POST  POST_info  ROM  info
babyface@bart:~$ ls /proc/acpi/video/VID1
CRT0  DOS  DVI0  LCD0  POST  POST_info  ROM  info

input: Video Bus as /devices/virtual/input/input3
ACPI: Video Device [VID] (multi-head: yes rom: no  post: no)
input: Video Bus as /devices/virtual/input/input4
ACPI: Video Device [VID1] (multi-head: yes rom: no  post: no)

Anyway, also tools like lspci should show you the fake vga device and
the X.org will complaint about it like:

(WW) intel: No matching Device section for instance (BusID PCI:0:2:1) found

And if you add this section (just for people who want to fix those
warnings) your X server will no longer start. :) Can someone correct me if
i am wrong?
