make several changes for video driver according to ACPI spec.

This patch makes two changes for video driver:
1. get display type from Device Attributes instead of device_id.
2. check whether the video device can be detected by bios or not.

There is another fallible place in your acpidump output.
The return value of \_SB.PCI0.PEGP.NGFX._DOD method is 16bit
while 32bit device attributes should be returned according to the ACPI spec.
This may be a bios bug, and video driver can not get the display type listed in
this _DOD method.
Can you try this patch and paste the result? :)
