On my Sony Vaio with latest linux-2.6 git kernel it says its a CRT :
[~]> cat /proc/acpi/video/*/*/info
device_id: 0x0100
type: CRT
known by bios: no
device_id: 0x0320
type: UNKNOWN
known by bios: no
device_id: 0x0410
type: UNKNOWN
known by bios: no
device_id: 0x0240
type: UNKNOWN
known by bios: no
device_id: 0x0100
type: CRT
known by bios: no
device_id: 0x0111
type: UNKNOWN
known by bios: no
device_id: 0x0118
type: UNKNOWN
known by bios: no
device_id: 0x0200
type: TVOUT
known by bios: no
So I don't think its reliable.
